The C7 Corvette rumor mill has been quiet the last month of so. Oh, a few weeks ago there was a burp about a possible C7 chassis mule hidden under a late model Corvette Coupe. (not much in that report) Then towards the end of May ‘11 CorvetteBlogger.com posted a report from TheDetroitBureau.com that the C7 would be powered by a turbocharged 3.0-liter V8. Of course, no one really knows except for the Chevrolet and Corvette engineers that are working on the project. But my take is that the little turbo engine report is pure speculation. There have always been those that have wanted the Corvette to be a small European-like sports car. I say, if that’s what you want, buy a Lotus.

Will Chevrolet back down from the 638-horsepower high-water-mark of the current LS9 engine? Let’s hope not. The computer emission controls on the latest LS engines seem to be more than capable of adjusting for horsepower, as we’ve seen from the work of Howard Tanner, the new “Mr. Motion” that’s building the official authorized, 800-horsepower  Baldwin Motion Phase III Camaros. (Yes, I have it on excellent authority that a Phase III C6 Corvette is in the works.) What might pull the plug on a mega-horsepower C7 Corvette power plant is the CAFE (Corporate Average Fuel Efficiency) standards. But since Corvettes are a tiny percentage of the average of all GM cars, they might be able to slip in a horsepower beast into the C7 to function as their latest, greatest halo car. It’s ALL up in the air and delicious fodder for bench racing.

But the turbocharged issue is interesting and got me to remembering an earlier turbo Corvette that Chevrolet was tinkering with. Back in 1979 the above show car Corvette was powered by a 195-HP L48 engine with an AIResearch tubrocharger that bumped the power up to around 280 – 290-HP. Why they didn’t use the more stout L-82 engine, only the Corvette engineers know. Ask Dave McLellan if you get the chance. But the extra 90-to-100-horsepower didn’t WOW anyone in the already husky ‘79 Corvette. But the car sure looked cool! The silver Coupe wore production front and rear spoliers, Continue reading “A Turbocharged Blast From the Past – the 1979 Experimental “Turbo Corvette”” →

Vette Videos: Zora Speaks! Zora Arkus-Duntov’s Last Public Interview

Former Hot Rod Magazine editor and publisher, Jim McFarland interviews Zora Arkus-Duntov in 1991
So, if you happened to have an extra $580,000, one of Zora Arkus-Duntov’s most famous “racer kit” cars could have been yours! The 1969 John Greenwood 427 ZL-1 BF Goodrich Corvette racer WOWed the crowd, but the bidders were tight with their bids. Very few people know how much the seller paid for the car in ‘06 when it was purchased from the Chip Miller Estate, or how much the restoration work by Corvette Repair cost. Suffice to say that the car was “well bought.” That’s auction-speak for “someone get a GREAT deal!”

Restored old Corvette race cars have become quite the prized possession for Corvette collectors. In early ‘09 the ‘63 Gulf One Z06 Corvette sold for an astonishing $1.113 Million. With the depressed economy as it is, it’s hard to say if the same car would fetch the same price today. No one knows for sure, but, ah, it’s not likely. What IS likely is that restored old “racer kit” Corvettes will continue to be high-profile machines at the auction, regardless of their sale price. From 1957 to the end of his working career, Mr. Duntov always made sure his beloved racers had “the good stuff” readily available from any Chevrolet Parts Department catalog. No one worked the corporate manufacturing system like Zora did and Continue reading “Vette Videos: Zora Speaks! Zora Arkus-Duntov’s Last Public Interview” →

Vettes at Monterey Auction Results… SOLD!

Published on by Scott

Dateline: 8.20.11
Buyers “Bought Well” at the RM Auctions Monterey Event

Well this was the first car auction I ever watched “live” online. I have to say that the interface on the RMAuctions.com was fall-off-a-log simple and played all the way through without a burp. The auctioneers were quite different from the local farm auctions where I’ve spend many a Wednesday evening. You could actually understand what the RM auctioneers are saying and they were so polite. Not that I was expecting an R-rated show, but it all was quite “proper.”

But a lot of fun just the same. And I appreciated how you got to see the cars rolled up on the turntable, so you got to see them from all angles. Plus they showed close-up interior, engine, and suspension photos. Most of the cars had been meticulously well maintained and restored. One 289 Cobra that had obviously been raced, had it’s original paint, minus a few scrapes here and there.  The auctioneer humorously quipped, “I just LOVE the patina on the original paint!”

The Greenwood #49 1969 427 ZL-1 B.F. Goodrich Corvette was the 44th car to go on the block. Most of cars 100 to 143 were “pushed” up and on to the turntable and those that were driven were so quiet you couldn’t tell if the engines were running. But as the Greenwood car was being introduced, there was THUNDER in the wings! They DROVE the open headered Corvette on to the turntable! When the ZL-1 was shut off, the auctioneer said, “It doesn’t get any cooler than that! 750-horsepower, ladies and gentlemen!” Corvette race cars SO ROCK!

Here are the five Corvettes that sold… Continue reading “Vettes at Monterey Auction Results… SOLD!” →

Engine History Made! 100,000,000 Small-Block Chevy Engines, and Counting!

Published on by Scott

Dateline: 8.19.11
Chevrolet announces the 100-millionth Small-Block Chevy engine to be built and installed in a ’12 Corvette in Fall 2011

Former chief of Chevrolet engineering and president of General Motors, Ed Cole.

This week Chevrolet announced that the 100-millionth Small-block Chevy engine will be built sometime in Fall 2011 and will most likely be installed in a 2012 Corvette! So three cheers to Chevrolet.

Hip, hip, HOORAY!
Hip, hip, HOORAY!
Hip, hip, HOORAY!

Although the small-block Chevy engine was designed to be an efficient passenger car engine, the design’s simplicity and durability has been providing Chevy fans with some of the fiercest engines ever. SBCs have powered just about every kind of race car from Indy and Le Mans, to drag strips and dirt tracks all over America.

Which SBC will be the magic 100 millionth engine has not yet been announced. It could be the mighty 430-horsepower LS3 engine used as the base engine for the Corvette, or possibly the most powerful production engine ever built in Detroit history, the 638-horsepower supercharged LS9 that powers the C6 ZR1 Corvette rocket ship. I’m sure that Chevrolet will make a BIG media splash about this car.

Enjoy our Small-Block Chevy engine gallery.

The man credited with designing and developing the SBC was former General Motors president, Ed Cole. As a youngster Cole liked to tinker with radio sets and was briefly a field rep for a tractor manufacturer before enrolling in the General Motors Institute where he got his degree in engineering. In 1949, along with GM’s Harry Barr, Cole developed the acclaimed 1949 Cadillac OHV V8 engine. By 1952 Cole was promoted to chief of engineering for Chevrolet. His first major project was the design and development of the replacement for Chevrolet’s tired, old, Stovebolt-Six engine. The finished engine was essentially a simplified, smaller version of the Cadillac OHV engine he’s helped design in ‘49.

When nested between the front fenders of the new ‘55 Chevy, the 265-cubic-inch, 162-horsepower engine looked, well, tiny. It probably only took a few weeks for hot rodders to realize that there was a ton of red meat in the little lightweight engine. The new small-block Chevy quickly developed the nick name “Mouse Motor.” Within a few years, the new SBC completely changed hot rodding and racing. It was, “good-bye Flathead Ford” and “Hello Small-Block Chevy.” Continue reading “Engine History Made! 100,000,000 Small-Block Chevy Engines, and Counting!” →

Vette Videos: 1973 4-Rotor, Mid-Engine AeroVette

Published on by Scott

Dateline: 8.13.11
Take a trip in the CorvetteReport Time Machine back to 1973 for a look-see at what could have been the first mid-engine production Corvette!

 

 

Chief of GM Design, Bill Mitchell had one order for designer Henry Haga, "Make it sleek!"

With all the chitter-chatter in the C7 Corvette rumor mill about a possible mid-engine Corvette, we thought it would be fun to take a trip back to 1973 for a look at what many thought would be the replacement for the C3 Mako Shark-styled Corvette. Corvette chief of engineering, Zora Arkus-Duntov had been pitching the mid-engine layout since the 1960 CERV I car. Not only was the AeroVette a mid-engine layout, it was to be powered by a 420-horsepower, 4-rotor Wankel rotor-motor engine. GM had licensing rights to develop the radical rotary engine that seemed to have a lot of potential.

The car's bi-fold gull wing doors made it fairly easy to step into the car.

In ‘73 there were two, rotary engine-powered Corvette prototypes. The XP-892 used a 2-rotor engine and had a body designed by Pininfarina. While it was a nice-looking car, it really didn’t shout, “CORVETTE!” The 4-rotor car was built on the chassis platform of a previous 1970 experimental Corvette that was simply known as the XP-882. The 4-rotor car definitely screamed, “CORVETTE!” Continue reading “Vette Videos: 1973 4-Rotor, Mid-Engine AeroVette” →

Let’s Play, Corvette Odd-Ball: FOR SALE – 1980 Four-Door Corvette

I’m sorry, but some things just SHOULD NOT be done. Back in 1963 a high-ranking GM executive got the bright idea that perhaps, Chevrolet should make a 4-seater Corvette Sting Ray. After all, Ford was doing pretty good with their Thunderbird that was once a 2-seater sports car, so why shouldn’t Chevrolet do the same, RIGHT?

Fortunately, this 4-seater Thunderbird fighter 1963 Sting Ray never went past the mock-up stage.

I’ve worked as a designer at Tyco Toys and Mattel Mt. Laurel in the R&D department and the ONLY way that bone headed ideas ever get past the verbal stage is if an executive makes the suggestion. Then you have to build one just to show the Mensa Society genius that it’s a dorky idea. A prototype 4-seater Sting ray was cobbled together and the story goes that an executive got stuck in the back seat and needed a lot of help to get out! I never heard of what happened to the prototype, but it probably went straight to the crusher where it belonged. Fortunately, that seemed to get Chevrolet off the four-seater Corvette forever.

So, is the four-door Corvette the solution to the “getting out of the back seat” problem? Oh, dear…

I’ve been highlighting odd-ball Corvettes for years now, and I believe this one gets The Grand Prize,” or maybe it should be the Booby prize. The car is up for auction on eBay and goes off  on August 10 at 12:06 PM. Continue reading “Let’s Play, Corvette Odd-Ball: FOR SALE – 1980 Four-Door Corvette” →

Interview With VETTE Magazine Founder & First Editor, Martyn L. Schorr – Pt. 2

Published on by Scott

Dateline: 8.1.11
An intimate conversation with Marty Schorr – Baldwin Motion, VETTE Quarterly, and other adventures…

(Our conversation picks up with an enterprise that’s still being talked about! You can catch Pt. 1 of this interview, HERE.)

Prototype 1968 Baldwin Motion Phase III SS-427 Corvette

ST – That’s a great segue Marty, let’s talk about the Baldwin-Motion experience.

MS – Baldwin Chevrolet was an old, local, mom & pop Chevy dealership. Joel was friends with John Mahler, the parts manager, and it all started out as a sponsorship with a strippo, red, big-block Camaro that they dropped an L-88 427 into and went drag racing. It was an advertising / promotion thing. The car ran great and we put our heads together and pitched a program to the Baldwin Chevrolet owners for a full line of supercars called, “The Fantastic Five” that included a Camaro, Chevelle, Nova, Impala, and of course, a Corvette.

We would start off with the biggest optioned engine and heavy-duty suspension and drive train, then we would drop in a 427 with a lot of hot rod parts. Because we were starting off with the toughest stuff available from the factory, the cars were amazingly durable, and still under warranty. We added aftermarket wheels, custom stripes, and badges that created a complete brand. The cars put Baldwin Chevrolet on the map and everyone made money. I did all the branding, catalogs, and ads, we had a shop do the custom stripping, and Joel did the conversions and final tests. Every car was guaranteed to run 12.5 in the quarter-mile with a professional driver. For a time we were the biggest specialty car maker under Shelby. When we got into the V-8 Vegas, Baldwin Chevrolet really didn’t want to have them branded as “Baldwin-Motion” cars because they were front heavy and didn’t handle very well. So if you ever see any of the Vega cars we did, you notice that they are “Motion Performance” car and not “Baldwin-Motion” cars.

Marty discovered that if he ran a hot Corvette on the cover of a magazine, news stand sales would improve. That's called "Corvette power."

 

ST – I was a teenager when you were splashing those incredible Baldwin-Motion and muscle car road tests in CARS. You assembled a group of writers that made the magazine something to look forward to every month. How did that all come together?

MS – When it comes out right, you’re a hero, otherwise, you’re a bum. The perception was that East Coast magazines only sold to East Coast guys. Remember that back then, because Hot Rod and Car Craft owned the newsstands, it looked like nothing was happening on the East Coast. The image was that the West Coast shops were these giant sophisticated shops – palaces – at least, that’s the way they looked in print. The first time I went to the West Coast I was shocked to see the Bill Thomas’ shop was just a little place. Dana Chevrolet only did their high-performance cars for about 1-1/2 years. Baldwin-Motion made cars for six years. The East Coast places like TASCA, SRD, Stahl, Baldwin-Motion, and Grumpy hardly got any attention at all. (Grumpy became one of drag racing’s rock stars after Pro Stock exploded in ‘70 – ST) And the editors of the West Coast books were all treated like heroes and you had to get an appointment just to talk to them. We had a lot to work with on the East.

Joe Oldham was a street racer kid that used to deliver flowers in my neighborhood and then one day he came into the CARS office to sell a Pontiac-go-fast article. It turned out that Joe used to deliver flowers in my neighborhood and knew my red Bonneville Coupe with the eight-lug wheels. Joe is now the editor of Popular Mechanics and for a long time was my road test driver and a columnist.

Roger Huntington was an engineer that used to write tech features for us. Not many readers knew that Roger had been wheelchair-bound all his life, but he wrote good tech features.

One of our early guys, Fred Mackerodt, started with CARS in ‘64 and today he’s a PR guy with a GM account. Fred was a very good editor even though he never graduated from high school. He was a good humorist writer to and used to do stories under the pen name of “Dilbert Farb.” (His trash truck road test had me in stitches when I was a kid. – ST) Cliff Gromer was another one of our regular guys, along with Alan Root, Alex Walordy, Stewart Yale, Fred Cohen, Joel Rosen, and others.
