Paul C started some great old threads.

I found this cuz I'm suddenly hunting for info on if the 63 Chev Z11 427/430hp was ever NHRA legal in S/S or AA/S, does anybody know?

I've heard not enough built, but by end 63 there were 50 or 57 built, same as the 64 HiRiser Galaxie and those ran NHRA legal AA/S=7.00 class from mid-1964 on.

Even if factored as high as 470hp, the Z-11 would still fit in AA/S at the NHRA weight I have of 3341 lb

So why dont we see any Z-11s in S/S or AA/S?
