The 450 HP came about because the L78 was rated 425hp and the L72 was 450hp but then changed to 425hp. They just used the higher number because it sounds better. NHRA rated the L72 at 450hp also.

JoeC;
That is also true.
My ironic thought was in regard to the fact that the advertising of 450 really only applied to the '67 427 Yenko Camaro's with a 4speed. The '67's were also available with the a/t, but were hydraulic cammed and therefore only rated at 410 horsepower. No mention on that board of the Super Camaro 410 [img]/ubbthreads/images/icons/grin.gif[/img]

However, it is referred to as the Super Camaro / 410 on the Span Inc. brochure. I believe this is the only hydraulic cammed super car from Yenko.

Marlin,
Didn't know that about the automatic Yenkos. I wasn't aware that the L72 was even available with the Hyd. lifters in 1967.
I do know that the early 1966 Corvettes with the L72 were rated at 450 hp, which ties the LS6 for GM's highest advertised HP rating.

They used the Corvette 390 horse version in the Yenko 410....BKH
