9. The Crower camshaft is a solid flat tappet as per Late Model Stock rules. It's ground with 252 degrees of duration on the intake lobes and 259 degrees on the exhaust with a lobe separation of 107 degrees and a 103-degree intake centerline. At the valves it should produce 0.561 lift on the intakes and 0.559 on the exhaust. This may not sound very radical for an all-out race cam, but Charlie likes to run his engines at very high rpm levels and says the cam grind is a balance between getting the most air into the chambers quickly and keeping the valves under control at high rpm levels.
