ponchjoe,
Sort of. Most cams are ground with the high point of the lobe roughly the same height (usually about.010” or so smaller) as the bearing journals. The way the lift is increased is by reducing the base circle. The difference between the base circle, and the peak of the lobe is the lift. The issue comes from higher lift has a smaller base circle, and this allows the lifter oil band to drop out the bottom of the lifter bore.
Thanks,
Stuart “Stan” Landreth
