Welcome to the site. The LQ4 seems to be the choice for boosted application
with 9.5 comp dished pistons. Many on here put a good used 02-04 ZO6 cam
in with aftermarket valvesprings for a streetable 8-9 lbs of boost on 93 fuel.
BTW how far from Claflin, KS are you ?? Knew some dirt streetstock racers
from there...Cates Brothers (Barry and Donny)
