Marko, i honestly can say that i cannot wait to actually see your car run!!. I've been build race cars with sbc's since before you knew where the battery in a car was located ..And I have yet to see a 355 ci motor with fulie heads run in the low 10's high 9's or 8's (i don't care how much NOS) unless in was in a rail Dragster ..So for this full bodied 69' camaro to do it that will be absoulty amazing:o ..Good luck!!
