So, why isn't it legal? Chevrolet produced 177 of these cars...that's right, CHEVROLET. Yenko Chevrolet got 175, and 2 went to Canada. Nothing fancy about them, just plain-jane Novas with the LT-1 & 4.10 gears, and your choice of transmission...granted, Yenko hung stripes/emblems on the majority of them (not all), but that was about as far as he went, unless the customer asked for more.
When I get home tonight, I'll dig out the Yenko-->NHRA correspondance and see about posting some of it. Then maybe someone can tell me *why* it never happened...
HERE IS SOME LIGHT READING ON '70 YENKO NOVAS
