I see what your saying. But I started out with the assumption my 401 was a 9.5 CR. I bought parts accordingly and took advice without proper knowledge of what I really wanted. My mistake and I am paying for it now by having to tear down my motor again. So heres where Im at. I want high 12's low 13's Can that be done by leaving the heads alone and knocking down the cam to the 214/224 grind adding the Performer intake and going with a 650 or 600 carb? Maybe even a 50 or 75 shot? Im listening, I really am. ------------------------ Yahoo! Groups Sponsor --------------------~--> Get fast access to your favorite Yahoo! Groups.
