Whats your guys opinion on the F cam, i have the valve clearance to run up to .580 lift, and i have .600 lift springs on the heads. would it be worth it run a X-cam with 1.6s instead of the F-cam with 1.6s and 1.7s cuz i'm gonna have sometime before i can put in the cam, I bought a Milodon 7 qt pan, i think it'll be smart to put in a Hi-Volume pump. and where can i get a hardened oil pump drive?
