Corvette ZR1: 1970-72 The Rarest Small-Block Corvettes Ever Produced


1971 Corvette ZR1

Out of all the years, the C3 Corvettes were produced, it's usually the '68 and '69 L88 big blocks that tend to grab the attention of the muscle car enthusiast. But the truth is that reaching for a 1970-72 ZR1 would be a much better Corvette to reach for if you're an enthusiast looking for that ultimate muscle/sports car

From 1970 to '72, the ZR1 was a limited-edition Corvette that was produced pacifically for the racing world. Only 53 were built: 25 for 1970, 8 for 1971, and 20 for 1972. These Corvettes are great investment cars, definitely poised for growth, especially the ones from 1970 when their horsepower was at its highest.

So what did you get with this Corvette Limited-Edition ZR1?

  • LT1 350ci. 370HP-suffix CTV-1970, CGY-1971, CKY-1972
  • J-56 heavy-duty brake package with dual pin front brake calipers
  • F-41 heavy-duty suspension package, 7-leaf rear spring, heavy-duty shock absorbers, heavy-duty 5/8 front sway bar, and heavy-duty spindle struts
  • Large aluminum radiator w/expansion tank (only LT1 to come with one so far)
  • Steel fan shroud
  • No radio, air condition, power windows, power steering, alarm system, rear window defrost, no special trim options.
  • And all the specialty options that were found on the L88s that were retired the previous year.

Designed to Race

Much like the COPO Camaro, the 70-72 LT1 Corvette was a rare rugged sports/muscle car designed to produce numbers at the track. Although one was designed to produce at the drag strip and one was designed to produce on road courses, they were both designed to race.

For a car collector who wants to make a good investment, the '70-'72 Corvette ZR1 LT1 is the way to go. The limited numbers produced, the most powerful Corvette of  '70-'72, and well, it's a Corvette makes it a great choice. Also, low options make for low maintenance: power steering, power windows, air condition, etc., can't go bad if you don't have them.

1966 Corvette 427 Big-Block "Muscle Car Era" Begins (Opinion)

Corvette 427 Cu-in

Corvette 427 Big-Block

Back in 1966, Chevrolet decided to get innovated and give the public something they have been craving – a small sports car with a huge motor. The Corvette was elected to introduce the upgrade that started a revolution of cars that would be labeled "Muscle Cars." 

Making the 396 Bigger 

Chevrolet created a feasible 427 cu.-in. motor for the Vette by taking the already powerful Chevrolet 396 cu.-in. motors and machining the bore and stretching the stroke of the block to a larger 427 cu.-in. This is the same way the legendary Chevrolet 327 cu.-in. engine came about. The Corvette's original 289 block was bored and stroked to a 327.

Big Block Hood

427 Big-Block Engines Were Available in Two Versions: 

  • L36 390 horsepower  
  • L72 425 horsepower 

Both engines were available choices given to consumers when ordering a Vette, and both engines performed sensationally depending on what kind of fun you were looking to have. 

The Extra Cost for the 427 Big-Block

  • The lower output L36: $185.00 Extra 
  • The higher output L72: $350.00 Extra

What Came With The High Output L72

The extra cost for the L72 would get you a better-structured motor that included: 

  • Four-bolt mains
  • Larger oil fitting ports 
  • Impact-extruded aluminum pistons (11.0:1) compression 
  • More aggressive solid lifter camshaft
  • Larger rectangular port cylinder heads 
  • Aluminum intake
  • Holly 780 CFM carburetor
  • Free-flowing exhaust manifolds
  • And a K66 transistorized ignition to help complement the other higher output parts. 

Although the L72 was rated at a massive 425-hp, it was a well-known fact the actual horsepower output was well above that publicized rating. The reason for Chevrolet's deception on horsepower numbers was to avoid unwanted backlash from the safety legislation. 

A Pleasing Power-to-Weight Ratio 

The 427 big-block Chevrolet motors were a tight fit for the Corvette, but the power-to-weight ratio was very pleasing for speed freaks. Plus, the much cooler big-block hood that came with the Corvette to make room for clearance, told people what was under the hood. Chevrolet would spend about six more years using a big-block powerplant with balls as an option for Corvette consumers. 

All Good Things Must Come to an End!

After 1972, the change to bring about more fuel-efficient cars would change what kind of powerplants all muscle cars would receive. This new change would eventually spawn the end of an era, the "Muscle Car" era. 

Cross Fire Injection Corvette

Small-block 350s de-tuned and ready to do poor performance was what the American car enthusiast would have to put up with for power through the '70s and '80s. In the late '80s and early '90s, change for more power started up again, and since then, there hasn't been much reason to complain. 

LS1 5.7-liter

The scary acronym EFI (Electronic Fuel Injection) has become a household name for all vehicle enthusiasts alike. And boosted and nitrous applications seem to run much better turned by a computer rather than by backyard mechanic techniques.

2020 Corvette Stingray Convertible: First Look

2020 Corvette Stingray Convertible

2020 Corvette Stingray Convertible

Although the Corvette is now recognized more for its speed and performance, through the years the Corvette’s heritage was mainly designed for comfortable convertible cruising. This 2020 Corvette Stingray convertible was also designed and engineered first-and-foremost around the convertible version. 

Back in 1953, the first Corvette ever available to the public was a convertible version, and that was all you were able to buy. Ever since then a hard-top and a convertible option has always been available, but this 2020 Corvette will be the first-ever convertible hard-top produced. 

Most people like the convertible hard-top version for its looks, but it also offers a few other great features. A quieter cabin, increased security, and an easy to keep clean and maintain tonneau cover are just some of the extra perks the convertible hard-top offers. Also for people who do drive their Corvette a lot, soft-top convertibles tend to need to be replaced after being exposed to the weather elements for too long. These convertible hard-tops are designed to last as long as the Corvette lasts.

The beautifully engineered 2020 Corvette Stingray convertible is still designed to fit two sets of golf clubs in the trunk plus an airline-spec carry-on and a laptop bag in the front storage compartment. For a supercar, that’s a lot of room a luxury you won’t find in other supercars. 

To make sure that the engine doesn’t suffer any circulation problems, the tonneau cover features aerodynamically shaped nacelles influenced by the housing used for jet engines. So although it looks like the engine may suffer from the convertible top being put down, Corvette ensures there is no engine power decrease.

You can activate the convertible top up or down at speeds up to 30 mph and it uses six different electric motors to get the job down in 16 seconds, a first for Corvette.

New Chevrolet Corvette ZR1 to Pace the Indy 500 - Here’s Why It Gets the Honor!

Image result for 2019 corvette zr1 Indy 500 pace car

Corvette ZR1 Indy 500 Pace Car

With its aggressive look and big bold front end and rear spoiler, this Corvette looks like it’s ready to take on every supercar on the planet, and with its overwhelming power and handling abilities, it is.

Let’s take a look at some of the 2019 Corvette ZR1 hard hitting numbers and influential features that helped it earn its right to be this years Indy 500 Pacecar.
The monster 6.2-liter supercharged V8 that sits under the aggressive looking hood of the Corvette ZR1 cranks out 755 horsepower. That horsepower combined with an eight-speed automatic transmission or a seven-speed rev-matching manual transmission pushes this ZR1 from 0-60 in just 2.8 seconds and covers the quarter-mile in 10.6 seconds at 134 mph. If that still leaves you a little under impressed, then maybe the 212 mph average top speed at the track in Papenburg, Germany can open your eyes to just how well this Corvette performs.  

What makes this LT5 ZR1 6.2-liter engine so much more potent than the Corvette Z06 6.2-liter V8? The engine the ZR1 gets has been upgraded with a bigger Eaton supercharger, bigger throttle body, a beefier camshaft and uses both port-and-direct fuel injection for an increase of 105 ponies over the Z06.

Image result for 2019 corvette zr1Helping this massive LT5 engine perform well even at high speeds for long periods of time is a much larger front fascia than the average Corvette. The ZR1 front fascia includes huge air dams and fender vents to help push as much cool air into the 13 radiators as possible. The ZR1 also offers plenty of other large exterior features. The front splitter is noticeably bigger than the Z06 front splitter and the ZR1 rear spoiler just dwarfs the ZO6 rear spoiler. Along with some other awesome carbon fiber add-ons, the 2019 ZR1 Corvette creates 950 pounds of downforce. Now it should be noted that if you don’t plan on doing any major competition circuit racing, you probably won’t need the massive rear spoiler, and if you think it looks intrusive, you can order your new ZR1 with a Z06 rear spoiler for a more reasonable look.    

So how does this turn-key race car drive as a daily driver with an average driver behind the wheel? When the Corvette is switched to Touring mode, you will get to enjoy a quieter exhaust, looser steering characteristics and a softer suspension. Outside of being very careful with the aggressive acceleration, this new 2019 Corvette ZR1 has the ability to offer you a very easy driving powerful supercar that leaves you confident in your driving abilities. And if you do want to test your driving skills at high speeds, the Michelin Super Sports tires and magnetic suspension offers you the same easy handling attributes at high speeds as it does in everyday driving situations. For a car that can reach 200+ mph and go 10 seconds in the quarter-mile, its ability to let you handle the car at ease at any speed is incredible. And of course, stopping has never been an issue with Corvette’s high performers. Six-piston carbon ceramic Brembo brake calipers are used in the front and four-piston calipers are used in the rear.  

Obviously, the interior of the Corvette ZR1 cabin is just as high-tech as the exterior and drivetrain. An eight-inch touchscreen infotainment center host all of the goodies and connectivity capabilities you would expect out of a high-end General Motors vehicle. Included with that system is a rearview backup camera, a front end camera so you don’t mash up your front splitter, and a powerful Bose system so you can jam away on long car cruises.

Coming Soon
The most powerful and capable Corvette ever built is now available at select dealerships. The full load of the 2019 Chevrolet Corvette ZR1 coupes and convertibles should be coming to all qualifying dealerships later this year/early next.

So what can you expect to pay for this 2019 Chevrolet Corvette ZR1? Around $122,095 for the coupe and $126,095 for the convertible (no word on the extra cost for the Indy 500 Special Edition).

2019 Corvette ZR1 Spits Out Flames Like The Batmobile

Corvette ZR1 Spitting Flames

In recent admissions from Chevrolet - they claimed that the new 2019 Corvette ZR1 will be capable of shooting flames out the exhaust pipes. No one really knew what that meant - would it shot out puffs of flames when you let off the throttle, would it shoot out flames at full throttle, or did it have some kind of flame-throwing device on it?  

Our questions are answered with this Chevrolet 12 second video. When the ZR1 LT5 powerplant is running at open throttle, beautiful whitish, blue flames shot out of the exhaust pipes. When the throttle is released, aggressive sounding pops are said to follow as the flames disappear.

All this can be contributed to the dual overhead cams on the 6.2-liter engine that promotes a 52 percent larger supercharger than what you will find on the current LT4 Z06. Also contributing to the light show is Chevrolet's first duel-fuel-injection system. And flames aren’t all this exhaust system does.

Image result for 2019 Corvette ZR1 at Nürburgring

The new sound flap that Chevrolet has installed gives the ZR1 an amazing sound, one of which is so loud, in some of the videos of the ZR1 running the track at Nürburgring in Germany, you can see that the exhaust system has been altered to point in a certain direction. The conclusion that can be made for the odd-looking extended exhaust is to point the exhaust sound away from the noise emissions meter.  Nürburgring has strict noise pollution levels that can’t be exceeded.

2018 Corvette ZR1: LT5 Overhead Cams

Related image

Nothing is ever set in stone when it comes to a prototype that has only been seen in camouflage, but as far as the ZR1 is concerned, we know that it exists, and more and more about it leaks out every week. It should come as no surprise that although the Z06 is probably the baddest American sports car on sale to date, the 2018 Corvette ZR1 will be just that much more badass.

One of the stretched out rumors that has just about come confirmed now is that the ZR1 will be receiving a supercharged LT5 overhead cam powerplant. Amongst the whispers about it for the last year from just about everyone, there are also other indicators. For instance, the massive tall hood is taller than any other hood that Corvette has ever used. This room the hood provides is needed since an overhead cam setup is much taller than an in-block cam engine. The supercharger is a no-brainer when you hear the Corvette drive around the Nurburgring track, the unmistakable whine gives it away.     

The other change that the video will show - believe or not - there will probably be an automatic option for the new ZR1 Corvette. When you hear the Vette whipping around the track, there is no doubt that the up and down shifts are so quick and precise that it’s not something that can be replicated by a human hand. What kind of automatic will be offered? Probably the 10-speed automatic that is offered along with the ZL1 Camaro.

Exterior options seem like they’re going to be broaden this time as well. In an attempt to bring in more sales, it’s highly speculated that there will be a convertible option. A lot of Corvette enthusiast may hate this idea, but the convertibles that Corvette has on the market now are extremely stiff and capable of handling a lot of power and tough cornering. It looks like there will be two different spoiler options, a bigger front splitter option and a few other hidden aerodynamic upgrades that are concealed by the camouflage. The reason for the different and bigger spoiler and spittler options could be because Corvette is in the works for a 1LE option like they have introduced on the ZL1.    

When can we expect a debut date? That’s still unknown, but as time goes on, we will probably hear and see more of the 2018 Corvette ZR1 assuming they’ll have to take it out for more and more test runs. There is a rumor out there - restated by Road & Track - there is a strong possibility that it will be unveiled at the National Corvette Museum.

Whatever the case, I hope it’s soon.

2018 Cadillac CTS-V What to Expect

Mainly what you can expect with the 2018 Cadillac CTS-V is what you could always expect from the CTS-V dating all the way back to its first release date in 2004. The Cadillac CTS-V sedan will be a beefed-up version of the regular CTS with the intent to compete with German sports sedans. Sedans like the Audi RS6, Mercedes E63, BMW M-5, etc. will all have to go toe-to-toe with this American-made monster. 

In the past, the Cadillac CTS-V has been able to beat those cars from the other side of the pound in performance and handling. But with competitors all wanting to be on top of the hill, the competition will be thick. The third-gen Cadillac will - as it has always done - use the engine and transmission components from the Corvette. 

The 6.2-liter Supercharged V-8 will push out around 640-hp+ and 630-lb.-ft. of torque+. Connected to an eight-speed transmission the Cadillac will be able to reach 0-60 in 3.6-seconds and reach 100 mph in just 3.9-seconds. General Motors rumors it as a car that can reach a top speed of 200 mph, but they have said that before. 

Some people may not be very happy with the automatic transmission availability (only), but the truth is, with technology these days, the only thing you gain with a manual transmission is the feeling of being in a car that feels faster. In recent years automatics have out-performed manuals in the quarter-mile on a consistent basis. And that's not just for the Cadillac brand, the Corvettes and Camaros have also been found to be faster with an automatic.  

Past years have left some people questioning the steering of the CTS-V, saying that it has been a little bit on the week and loose side. Supposedly Cadillac has addressed these issues and the steering is now much more hefty and precise. With GM's new Magnetorheological suspension and huge Brembo brakes, the 2018 Cadillac CTS-V should have no problems handling any performance driving you throw at it. 

In true Cadillac fashion, like all of the other CTS-V sedans, even with the massive engine under the hood and other power upgrades, you will still be able to drive this vehicle back and forth to work, to the golf course, and even take them on long trips with every luxury every other Cadillac offers. 

For all of the new CTS Cadillacs, including the V-Series, they will be receiving a new infotainment system that is supposed to add more capabilities and be more compatible with the ever-turning technology age. Other interior upgrades the CTS-V will receive is a sportier steering wheel, and that's about it. For the most part, from the inside to the outside you will be owning a CTS except the emblems will have a dash and a V added to them and the power will be enormous. There will be somebody improvements, but hardly notable.  

There is one last thing to mention - this is about as big as a rumor as you can get - but a rumor is a rumor. Since all other vehicles in their class have two different body styles, there has been some talk about a possible addition of a wagon or a sedan to the 2018 Cadillac CTS-V line up, but that's just a BIG rumor. MSRP expected to be around $86,000.00.

1996 Corvette Grand Sport: Throw Back to the '63 Corvette Grand Sport

Related image

When it comes to fourth-generation Corvettes, they shared a common trait with all other American Sports Cars at that time, their power was not all that impressive. So when it came to the fourth-generation Corvette's final year (1996), Chevrolet decided that putting something special on the market would be a boost for their brand and bring big attention to the on-deck sixth-generation Corvettes of 1997.

To bring the spotlight back to the Corvette, Chevrolet's solution was to go back to 1963 when they made one of their meanest Corvettes of all time and revive the name and color scheme. For 1996, Corvette decided that 1,000 models would get special treatment for better performance, a louder color combination, and they would place the Grand Sport badges on the Vette just like they did in '63.

Giving the Corvettes What They Needed
Corvette engineers slapped the 1996 Grand Sport Corvette with an LT4 that originally pumped out 300-hp, but for this special edition Corvette, engineers managed to squeeze 30 extra horsepower out of them. They accomplished this with a more aggressive camshaft, higher-flow aluminum heads, larger valves, higher-compression pistons, new high-flow fuel injectors, and roller rocker arms.

Crazy colors followed – Admiral Blue Metallic paint was accented with a big white stripe that ran down the center of the body. Two red hash marks were placed on the left fender and matched the red interior. Black painted five-star rims completed the color scheme and made up the Corvette that some people ended up loving and some people ended up hating.

Grand Sport Corvette Handling Options
When it came to performance handling, the 1996 Corvette Grand Sport didn't get much more than the original standard Vettes did except for a bigger set of tires for the coupe: 275/40ZR-17 Goodyear radials in front and 315/35ZR-17s in the rear. The convertibles received the same size tires as the non-Grand Sport Corvettes did but there were options. 

On the 1996 Corvette Grand Sport, just like with other Corvettes, you could spring for the $350.00 Z51 handling package which came with stiffer springs, new Bilstein shock absorbers, and front and rear stabilizer bars. There was also an optional Selective Real Time Damping system that cost an extra $1695.00. That system used sensors and accelerometers at each wheel to give the semi-active suspension the ability to readjust the shock damping in 10-to-15 milliseconds, sort of what they use today on the Corvettes just not nearly as sophisticated.

All-and-all, I always loved the look of the 1996 Corvette Grand Sport, it's one my favorite from the fourth-generation, although there wasn't much competition. The next year Corvette changed its style and engine, and the left over LT4s motors found their way into the 1997 30thAnniversary Camaros.

Mid-Engine Corvette Going To Happen - Update

Updated Again: 10/8/2018

So a quick update on what could be one of the most exciting automotive days in my life. Living in the Motor City there has been a lot more talk that seems to be more fact than fluff about the new Mid-Engine Corvette.

Car and Driver, The GM Authority, Auto Week,, etc. has all been posting on what might be - but I like facts. From sources I can't mention, the word is there should be renderings from Corvette designers (renderings that matter) out as soon as later this year and prototypes at the North American Auto Show in January of next year. And if anyone knows how Corvette does business, when they put something in the North American Auto Show, even if it is a prototype, that means unless something goes drastically wrong, it's going to make it into production.

My hope is Corvette (GM) takes a page out of the Ford Motor Company's play book and does something similar to what they are doing when it comes to purchasing-eligibility for the 2017 Ford GT supercar. Clients who want a chance to get put on the waiting list for the limited-edition Ford GT supercar have to fill out an application. The idea behind the application is to make sure that people who purchase one of Ford's limited-edition supercars will drive it, take it to car cruises and car shows and not stick them into their personal museums to be dusted off 20 years later and sold at an auction for profit. 

Along with the above-mentioned reason, most auto companies that create such wonderful works of art usually store a few of those priceless cars in their own museums anyway. Ford Motor Company, as like most auto companies want to see their vehicles driven, they want to see their beautiful designs being used for what they were designed for, having fun in them.  

But time will tell what happens, the closer Ford comes to getting their supercar out, Corvette will push harder to get their mid-engine Vette rolling and hopefully the competition will roll on harder than ever. 

I have talked about the mid-engine Corvette in the past, its possibilities of finding its way into the Corvette lineup and what it would mean for GM, Chevrolet and Corvette. After many exciting years of maybes, it's possible, it's just a cool thought and nothing more – the Godfather of the Corvette, Zora Arkus-Duntov, has made it pretty clear that the public will see a Mid-Engine Corvette revealed possibly as soon as the L.A. Auto Show late this year.

Although this would be new to the public eye, it is a well-known fact that Corvette has been working on and has come up with a pretty permanent version of a Mid-Engine Corvette. The drivetrain solutions are said to include a seven-speed manual transmission and an LT1/LT4 700-hp twin-turbocharged engine.

Unfortunately, the many renderings I have seen, which is not much to my surprise, looks almost just like a Ferrari with Corvette badges. And I say not much to my surprise because if you look at a 2016 Corvette Z06 and compare it to a 2016 Ferrari F12, put them in the same color, you can very easily mistake them for one another from a distance (my opinion).  

When this does happen, the word out is that most of the front-engine Corvettes will still be very much a part of the Corvette lineup and most likely none will be bumped out as a result of an extra Corvette coming in. The front-engine Corvette is part of the iconic brand as we know it. If anything, the Mid-Engine Corvette will be more for just breaking track records, giving the Ford GT and other Mid-Engine competitors a run for their money, and or to sit in a rich person's car collection.

When the Mid-Engine Corvette does become an available vehicle for the public to purchase, you won't be able to just go to any dealership and buy one or have one serviced by any dealership under warranty. Selected dealerships with a great reputation for sales and customer service will be high on the list of places that will have the honor of selling and promoting the Mid-Engine Corvette, and of course, three other things will help decide where they will be available at – location, location, location.

The price tag for one of these Corvettes is going to most likely be out outrageously high. That is why location will be a huge part of deciding where they will be sold. If Corvette is thinking about competing with the Ford GT, and when has Chevy ever not tried to compete with Ford, the price tag will likely find its way up into the $350,000 to $400,000 range. That is a supercar status price tag, but Chevrolet has yet to fail on any attempt to make a sports car or supercar worth every penny in the past 10+ years.

2017 Corvette Zora C8 Mid-Engine Possibilities

If you are that person who has been hoping and waiting for a mid-engine Corvette, your Corvette may be on its way sooner than you think. Many sources like Car and Driver and GM Authority claim Mark Reuss, head of GM's Global Product Development confirms that the company is already working on the next generation Corvette.

As of now, the C8 Zora-ZR1 mid-engine supercar is being pushed to make a 2017 debut. Estimates of  about $150,000 average price tag could be what Chevy will be looking for, and about only 1500 units will be built, much like ZR1 C4's and C6's.

Why the Push for a Mid-Engine Vette
GM claims there is two reasons for the push of the mid-engine Vette. One of those reasons are after tweaking all of the power that they did out of the ZO6, they realized that they would not be able to put any more usable power into the front-engine Vette because the tires simply just will not handle it.

GM also believes that a mid-engine Corvette could bring in a newer, possibly younger customer base. Instead of a big shot corporate man in America showing his success and his taste for the finer things in life with Porches or Ferraris, maybe a mid-engine Corvette could serve the same purpose.

Well, nothing is set in stone, but there should be no reason to worry that you might see a 2017 V-6 Corvette anytime soon. Sounds like a single cam V-8 with direct injection and shut down cylinder displacement will still be what's on the horizon. As for a power rating and or what kind of aspiration will be used is yet to be known.

There has been rumors that as government fuel consumption clamp downs become more and more an issue to car designers, we might see a 2020 mid-engine Vette that could host a V-6 that would leave room for an electric motor that would run the front wheels making it a four-wheel drive hybrid Vette.   

Cockpit and Cargo Space

A mid-engine Corvette will give the luxury of giving the driver and passenger better forward sight lines since there won't be no reason for having an elevated hood. But that also means your view looking backwards will obviously be hampered.

There is also a lot of questions about luggage space. Where will the gas tank go? If it gets located in the front, will there be space for golf clubs, luggage, etc.?

I guess time will tell, I'm sure GM does not even have a clear answer to how and where the transmission, trans-axle, radiator, and exhaust will fit.
