70 COPO

What HP did the 350 duece have? Not being smart, just wondering cause the last time this conversation came up someone mentioned that the 70 Copo Z's were not in the supercar class as they were small blocks and I did not think of the Deuce's then!

Of course, now that I have one I am a bit biased

The Yenko Deuce Novas have the Z28's LT1 - including the same application codes for 4sp & a/t's. The Deuce is a SuperCar bec/ the COPO #9010 & #9737 were drivetrain performance items, whereas the '70 COPO Z's were a spoiler change. If I recall the debate, it was regarding whether the spoiler change was considered a performance enhancement vs. an SCCA homogulation requirement.

Either way, both are cool cars - but then, I might be a bit biased too

Marlin,

I knew you would chime in!! Clairification-As I recall the Deuce was created to beat the insurance companies as they attempted to rate hike the supercar out of existance-that is why there was no Big Block Yenkos built in 1970. Right?

They were and are both very cool cars, both getting the LT-1 from the "Corvette" option list.

I'm sure Don had several reasons in mind for the Deuce copo's, one of which we feel was also SCCA homogulation - hence the similarities to the BOSS 302's. There were plans for Yenko big block products in '70, but alas, there were plenty of '69's on the lots!

Don't confuse the motives of Yenko with GM - I don't think GM created the copo to beat the insurance companies GM approved the Deuce copos bec/ Don was buying 'em.



There might just be a showdown on SCR9 betw/ a Deuce and a '70 Z

Marlin,

Sorry do not want to go too far off topic - but just one more question for you. I know there were Canadian Nova COPO LT-1 cars sold also. Were there any non Yenko Converted LT-1 Nova's sold stateside?

Phil

There were indeed two that went to Canada, with one surviving. We do not know of any that were sold in the US outside of Yenko's orders. However, most who have discussed this topic at places like the SCR's believe that the possibility is quite high, but without any special identification it would be hard to identify them.

I Agree! 360hp out of a 350 stock?!
FWIW, Did'nt the LS5 454 have 360hp?

Phil, which one of us is going to take Marlin up on that offer?

Rich,

Gee that is a tough one. Marlin runs the most consistant 14.4's that I have seen. Seriously-I cannot bring myself to risk the original drivetrain. You know perhaps if I had blown the engine up earlier in life, I might be more risky with it, as you may know in the LT-1 7500 comes up really quick and things get scary fast at those RPM's.

Original motor in your car?
