Valvetrain: Pushrod Selection and Installation

tech-PicThe 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. At the tip of the balls is a small hole used for oil transfer and lubrication to the where the pushrod meets the underside of the rocker arm. There have been numerous changes made by aftermarket companies to further improve on the design for specific applications. Although they are all basic in form, there are many facets to the selection of the right pushrod for any high performance motor.

Let’s first take a look at valvetrain geometry and its effects on the function and performance of your engine. When installing a new set of rocker arms or pushrods, it is crucial to obtain the proper working geometry in the valvetrain to maximize your engine’s power potential and reliability. There must be ample clearances for all moving parts of the valvetrain.

It’s the first thing we see when we get in and the last thing we grab when we are getting out. We present to you: the steering wheel.

The above mentioned scenarios are but a few of the ones we have seen and, well, if the truth be known, participated in.
