Valvetrain: Pushrod Selection and Installation

The pushrod and its role in the valvetrain is an often overlooked, yet vital piece in the puzzle of high performance. It is the translator of cam and lifter movement to the rocker arms and valves. Bridging the gap between the two, the pushrods are held responsible to deliver the exact orders of the camshaft without flex or deviation. Most factory-style pushrods were constructed with a welded-on ball tip on each end of the rod.
