The cam is a custom solid roller ground by Comp Cams (.730/.704-inch lift, 253/256 degrees duration @ .050 on a 107 degree LCA). Dick felt the engine could have used a larger cam. This one ran best with valve lash at .010-inch on the intake side, and .012-inch on the exhaust. With 107-degree lobe separation, the cam was installed with 3 degrees of advance. Dick asked us not to print all the cam specs, since such things are proprietary among Olds enthusiasts. As with all the components shown, these parts can be purchased at Dick Miller Racing. This particular camshaft design is part of a new crate engine program from DMR.
