The camshaft features 230 degrees of duration on the intake side and 236 degrees on the exhaust side, measured at .050-inch lift. Max lift is .510-inch on the intake lobes and .520-inch on the exhaust, when using 1.5:1 rocker arms.

Can a flat tappet camshaft be converted to a hydraulic roller?

The COMP Cams 853-16 retro-fit hydraulic roller lifters are the key to this conversion, as they offer a link-bar design to slide directly in place of the original drop in flat tappet lifters. After applying installation lube on the rollers, we dropped the lifters into the bores.
