Default Re: 68 Yenko clone

Pete, Bob Wayne and all who have helped weed out the basic facts

I am now where I want to be with this and know a pantload more than I did last week.
I found this article about the #8021 and it states from the current owner "For 1968 the 9737 COPO comaro was only available to Don Yenko and in fact Yenko was considered the manufacturer for these 68 Yenko Camaro's. However this #9737 COPO package was added in 1968 as per Don Yenko's request to RPO L78 SS Camaro's that were equipped with the 396/375hp big blocks.
The COPO #9737 designation added for 1968 cooling, suspension and brake upgrades along with a 140mph speedometer, heavy duty springs, larger anti roll bar, M21 tranny and a 4.10 posi rear diff. These 9737 COPO's 1968 camaro's were delivered from Chevrolet to Cannonsburg with RPO (regular production order) L78 396/375 hp engines. Yenko's mechanics then removed the L78 396 engine and installed a L72 short block. The original L78 heads and aluminum intake and carb were then installed on the L72 short block." end quote. author unknown, but pulled from the Las Vegas Clasic cars website.

I would assume this to be correct and still leaves 6 cars not known from the 70 ordered As far as the comment about why not auto's is not a strength issue (as I have put 1200hp through a T400) its just that they all came with an M-21.
