Our cam is a Crower piece, and is a hydraulic roller design. It carries PN 01406, and the specs are serious. The intake side gets .636-inch lift with 309-degrees of duration, while the exhaust side will see .658-inch lift and 310 degrees of duration; all with 1.7:1 Crower roller rockers. Lobe separation is 110 degrees, and duration at .050 inch is 253-degrees intake and 260-degrees exhaust. It'll be able to idle just fine at about 850 rpm, which is plenty streetable by our standards.
