I remember someone saying the 074 heads made about 8.5 comp with closed chamber heads. Someone said 10.0 with closed 11.0 pistons. Which is closer? We are doing this with a 30 over L72 short block. The car has the makings of a nice street brawler but no more to me.
A little late but we are using the factory type 30 over 11.0 to 1 pistons Bryon.
