Building on the short-block assembly starts with the camshaft. For better streetability, it's a hydraulic roller from Comp Cams and, with 242/248 degrees of duration at 0.050-inch lift, it's not unruly. To take advantage of the displacement and a set of big-flowing heads, the lift specs are 0.540-inch on the intake side and 0.560-inch on the exhaust. The lobe separation angle is a middle-of-the-road 110 degrees, balancing slightly more valve overlap with a decided lope at idle.
