396ci Chevy Big Block - Engine-Building Tips
The lightest piston sets the weight that every other piston must match, since material is never added to a piston during the balancing process, only removed. Material is removed from the wrist pin lugs where it will not impair the overall strength of the piston. Not only are the total weights of each rod matched, but so is the weight of each end of each rod. This is accomplished by grinding material from the pad at each end. Before the crankshaft is balanced, bob weights filled with lead shot to match the weights of the reciprocating components (pistons, rods, rings, etc.) are added to each throw.
