496 Short Block Top End Engine Build Thrust Adjustment

With the cam in, we could adjust for thrust. Barkley derived a failproof method for measuring for cam thrust with a piece of duct tape since these timing covers have no hole for a dial indicator. The thickness of the duct tape is a perfect budget-indicator for determining the exact measurement since it is about 0.030-0.040 inch thick. With the tape on, we bolted the cover and found a perfect indentation imbedded in the tape surface. Our cam had correct thrust, and we peeled the tape to bolt the cover for final.
