The camshaft is a Comp No. CRH 300-7-295-4 R110 (measuring 268/264 at 0.050-inch and with 0.650/0.630-inch lift), may seem "big," but with 572 ci soaking it up, the combination is more than docile enough to work well on the street. Engine builder Ken Lazzeri considers it "mild"-and it is, compared to the full-race combos put together by Indy. Ken described the idle as "smooth." The roller lifters are Comp No. 829-16, while the springs are Comp No. 26115-16, delivering 210 pounds of load at 2.10 inch. The tall installed height, and moderate spring loads provide longevity and control. Comp titanium retainers help lighten the weight load at the valve, and are 10-degree units for use with Comp's 10-degree SuperLocks.
