Big Blocks

not sure i follow you on the 440, why would you reduce c/r when your going to a larger cam? a larger cam needs more c/r to keep the cyl psi up, the 440 hp numbers are very low i've put together a few bb with the same setup and hp was always around the 430/440 mark, Are you running the total timing low or jetting it on the fat side to stay safe for street? just wondering.
