I'm looking at these 2 Howards cams 723445-10 235/241 @50 545/545 on 106. 723235-12 243/247 @50 600/600. on 108. My springs are set @155@ 1.88-1.89. [email protected]. My new build is pump gas 511 RB shooting for about 10.3-4/1 comp. I have EZ heads standard port. PRH valve job w/back cut valves, blended, ported chambers. I have 3 choices of intakes M/1, Torker II, TM7. I'm not looking to squeeze every ounce of hp just easy on parts and low maintenence. Too many horror stories about flat cams that's why I'm thinking about going roller. I could go old school and throw the MP .557 I have that's already broke in.
