i know with a 20cc head its 9.2.. so you should right around 10.1. thats awful low for a N/A stroker.

then you might want to think of lowering hte compression some more for a boosted motor unless you dont plan on making large numbers or you want to live on race gas

i think the compression is hurting you. you run the ms3 its a good cam. your combo is nice but since hte compression is roughly 1.5 pts lower then it needs to be you are leaving a good bit of power on the table. you might be 450 right now. if compression was higher then you would probably be at 500 or higher. its hard to honestly guess. best is dyno

6speed isnt hard to do but when behind a stroker it will eatup a stock t56!!! its a costly swap when dealing with a big motor
