I still havent purchased my cam for my .040 over 351W. When the motor was built a few years ago it was built with a stock valvetrain. So it has a hydraulic cam, and lifter setup. Do you think i should step up to mechanical lifters and cam instead so i dont have to worry so much about floating a valve? All i would have to do is change out the cam and lifters right? how about the pushrods? thanks guys!
