Mark is right on with the .630/.630 cam with 106 L/C, i have one and installed it @ 102 lot's of HP with that cam. In my 434" motor with Lanotti promod rods i have .734 lift with 1.6 rockers, but Bullit ground the base circle to .870 for clearance with the rods. A .660 lift will fit with eagle rods and .900 base circle, from personal experience.
