Tim, the cam lobe specs are accurate. It's Howards top duration and lift profile for the FH. The lift and duration, is a product of lifter diameter and the maximum lift velocity for that size lifter. SBC, .842 lifters, lift velocity, isn't even in the same universe as a 1" flat heads lifter. If you were to use these Howards FH cam profiles, with a 1.6, or greater rocker arm, you have valve events, that will beat some roller cam profiles.

Frank,
The lift figures of that Howard cam are very similar to ones used by the DO Hal for mile track events.
