I've got a motorhome 440 with next to no miles on it, with the way down in the hole cast pistons. I'm putting an aluminum Edelbrock intake and 1 3/4 headers on it. Instead of changing the cam, would it be worth installing 1.6 rockers to bump up the lift of the stock cam? I'm imagining that the increased lift would help with the breathing, but no extra duration might keep the dynamic compression ratio from dropping too much? Am I off my rocker?
