496 Short Block Top End Engine Build Aftermarket Crankshaft

With the heads on, we slid in our Thumpr cam from Comp, chosen for its 2,500- to 6,100-rpm operating range. Not only would the motor make great bottom-end grunt, but with the amount of intake and exhaust valve overlap we could harness that great muscle-car idle. Our cam came with 243/257 degrees of duration at 0.050 and 0.570/0.554-inch lift (intake/exhaust). We lubed up the cam and, using a cam installer, locked it in, making sure not to ding the bearings.
