Note: Due to differences in cam base circles, deck heights, head milling, gasket thickness, rocker arms, etc., actual push rod length can vary. Pushrods are sold for the experienced engine builder. We recommend you assemble the motor first and then determine correct pushrod length. One of the best ways is to grind a stock pushrod until you get correct geometry, measure, and order one closest to that size.
