Nowhere Man

Bill Grumpy Jinkens is the one who I think your thinking of. I know there was quite a few special cars came from that dealer.

Jenkins was a MK1 427 builder for Strickler in the early 60s (1963). But left Chevrolet with the advent of the racing ban. When he came back to Chevrolet it was more for the match racing and he was running small blocks (thus the nickname Grumpy's Toys), but simultaneously worked on development of the big block. He did his part in history on that.

Grumpy was actually the author of technically the very first Chevrolet Power book, which wasn't named power. I have the 1971/72? dated book on the Small Blocks that was the prototype of those Performance parts books at home! It kind of has a lot of Green on the front cover. I have never seen another. Ok maybe if everyone is super nice, I will post up that book cover also!!!!! But say pretty please, with Holley on top! Rodriquez drove the Best of Chinetti's stable of Ferrari cars in the 1966/67 years!

Funny how they leave the real Harold Whims HD car out of the four Horseman story (the White #8 car with the cut open side vents at Sebring). Pedro R did not get handed any super special Chevrolet race car!!!! He didn't hook up with Yenko until after he went independent of Chinetti, and was racing F-1 with like BRM, and he got a production car from Yenko to drive later and shared the C3 drive then with Don! His basic separation from NART led him to the Wyer Gulf Team!!!!!!!

That was their newer marketing of the performance parts from 1968- 1972! I have one of those water transfer decals on the back glass of my 68 C3! And I have that very catalog too! Jim Osborn Reproductions was still offering a copy of the latter 3-9-1972 edition of that catalog for the Special Chevrolet Equipment, and they pop up on EBay! I have been saving my original catalogs and the ones my Father sent away for (for 50 years). I have all of the Nickey, Berger, Motion, Briggs, Bill Thomas, Power Books, GM Performance catalogs etc etc etc

The 65-67 was the Yellow and black stickers and patches Genuine Chevrolet High Performance Parts! The ornate Genuine Chevrolet Parts was the more script earlier patches and stickers till about 1965, then just Everything was under Genuine Chevrolet Parts in also the bow tie Yelliw and black patches and stickers!

I lied to everyone!

The Green book was early 60s Performance and the Jenkins book is the tan colored one on the right! Sorry! As I get older, I am getting senile and forgotten much of what I used to know or what I own!

I have a lot of this type of stuff and more than pictured, having been into Corvettes and Chevy muscle for 50+ years! Cool stuff! At least I think so!

But back to cars!

I do consider the Penske car as an L88 of the 425hp HD variety, but initially having aluminum heads! They made multiple attempts as I have detailed in other threads to get the aluminum head problem solved, and ran the iron heads at both Daytona and Sebring! The Best Photo Yenko brokered car looks to be another effort to run the L88 aluminum head engine! This car I can't verify if it was a pilot line car (escorted down the production line specially fitted or whether Yenko was shipped an L88 engine for install! The Proving car was a test mule and the promised new Competition model and used for trying to work out the aluminum head problem, and the press were invited to the proving grounds and that was the basis for the Dec 1965 Car Driver 12.8 112mph run! This car had a special tach!

From perspective, the Yenko Coupe #8 White car I have never heard or seen anything related to that car having aluminum heads! And what Yenko got and did is very poorly documented! He was not a magazine favorite or a guy that drew the press! His biography is poorly written, and I could do a much better job than that author, but a lot of just mysteries to solve on his stuff! He got the 1967 DX L88, which beat the earlier Delorenzo roadster out onto an actual track! That Delorenzo car does prove they were willing to put L88s in Convertibles, but the Coupes seemed to be the more preferred choice! I am even starting to think that the DelorenZo, the Yenko DX, /'and the LeMans racer were built up from shipped special L88 engines and parts and not factory assembled based on pictures of the Le Mans car getting build! I posted for you guys one of those photos of Guldstrand about to drill the hood that no one but me has ever shown! I have a lot of rare not seen stuff, like a picture of Guldstrands South American Trans Am Camaro!

I think the Yenko Whims white car was a run up the production line build HD car in preparation for fielding it at Sebring! The #67 car was special ordered for the purpose of racing it, but was lacking getting some of the special things! If it was a special supplied by Chevrolet factory race car, it would have had everything they had to put on one, like J-56 etc. I personally think they finished in the shop building it up into a race car! That engine was basically L-72 stock! If they weren't trying to field it for Daytona, they might have gotten a better car! The 4th car was other built up into a racer!
