sorry but it takes a good foot and lots of HP to run 12.2 in a ZR-1
the automatic is an advantage. so up top, you'll spank him but in the 1/4 mile, 12.2 is a pretty stout time.
I've seen some stock zr-1s go that fast (dave/jeff/s black car went 12.08 in ideal conditions with Jeff driving, headers only) and curtis
but for comparison, my 508 LPE goes 11.45 @ 127 with folks more talented than me driving. I usually run 11.7-12.0 at 124 - 127
soooooo I'd think twice before you brag too much.
