Here is an interesting quote from the BJ site

“Bring the worldwide resources of Barrett-Jackson Auction Company to your service with the widest selection of pre-screened automobiles in top quality condition, and at market-relative prices. Barrett-Jackson is also the only auction company to offer an on-site detailed vehicle inspection, available to consignors and buyers.”

With the claim of “ pre-screened automobiles in top quality condition” and “ on-site detailed vehicle inspection” you would think they could weed out the obvious fake paperwork and trim tags.

Yenko was also working on a X-11 Citation project. Yenko Sports Car Inc was doing some race development on it and in some of the pictures there is this long hair guy with glasess working on the engine. It was Bill Grumpy Jenkins.
A writer for one of the mags was there and took some pictures and years later did an article on it.

Some of the paperwork in the ad says it has a Ray Jay Turbo then other paperwork says it is a TI Turbo which I believe that is what they used. TI is Turbo International
On a side note 1981 was about the end of Yenko Chevrolet. It then became Sun Chevrolet.

In Smokey’s book, I think he claimed something like 200 sets of the porcupine heads were cast.
Not sure how many had final maching operations done, but Chevy would have to have a good number of heads in the pipe line if they planned to run this head configuration in Trans Am. The rules to homologate parts for TA stated that the items had to be available to the public in sufficient quantities. So Chevy had to make a pretty good amount of Z race parts such as cross rams, big sway bars, 4 wheel disk, hoods etc.
TA rules allowed service parts but they had to be pre-approved by SCCA.

also on ebay were the
FORD TRANS AM TUNNEL PORT CYLINDER HEADS

Chevy was working on the Porcupine head as a response to the Ford Tunnel port head. From what I read, they both made good power but at higher RPM so there was less low RPM torque for pulling off the corners and the higher engine RPMs hurt engine reliability.
 The Ford Tunnel port heads were not very successful and had a lot of engine failure so the Porcupine heads were not really needed.
It's amazing the extent that Chevy and Ford went to just to win in Trans Am

Don Yenko was working on projects with Chevrolet similar to Shelby was with Ford.
 Yenko had the FIA/ACCUS manufactures license to remanufacture Chevrolets as Carroll Shelby did with Ford and raced them in SCCA. Yenko mostly liked to race Corvettes and received many special Corvettes from Chevy that he raced beginning in 1961 and was National Champ in 62 and 63.
 The SCCA class racing was for two seat sports cars and they required 100 cars to be manufactured to homologate the model for production racing. The Shelby GT-350 was not a Ford in the eyes of  SCCA. It was a 2 seat sports car manufactured by Shelby American. Same with the Yenko Stinger. It is not a Corvair to the SCCA. It is a 2 seat sports car named the Yenko Stinger manufactured by Yenko Sports Cars.
 Yenko had to qualify and show proof of a manufacturing facility and personal to be recognized as a manufacturer by FIA and ACCUS (Automobile Competition Committee of the United States) and build the 100 car minimum. Same as Shelby did.
As far as I know Yenko was the only Chevy Dealer to have this FIA/ACCUS manufactures license.
Chevrolet and Yenko tried to use his FIA/ACCUS manufactures license to qualify the 1967-68 Yenko 427 Camaro for the NHRA Super Stock 50 car factory built minimum. NHRA would not approve it . The Yenko 427 Super Camaro was approved for AHRA Super Stock in 1967 but not NHRA.
In 1969 Chevy did the 427 COPO Camaro and Chevelle to meet the NHRA 50 car minimum and marketed them through Yenko Chevrolet and other dealers.
Yenko did the paperwork with the FIA to homologate the 1969 427 Camaro and raced a ZL1 powered  69 Camaro at Daytona and Sebring in 69 and 70.
Yenko and Shelby were racing buddies in the SCCA for many years.

hello everyone - my first post here

Sounds like an interesting Camaro
Does it have the original grill and if so what color is it?
