Looking at options for a cam package for a 426 Hemi. My machinist is suggesting a mechanical roller set up. It's all new to me. I've always had 440's with a hydraulic cam. Any suggestions for a good quality cam, lifters, etc? Hughs? Comp cams, ??? This engine will be street driven as much as possible with an occasional blast down the track. An 18 spline 4 speed and 3:54 dana 60 make up the rest of the drivetrain.
