Correct valvetrain geometry is critical to ensure trouble-free operation of an engine, especially during high-rpm operation. When building a new engine, many people simply reuse the original pushrods ...

If you are into precision engine building, you've no doubt heard the standard line for establishing the proper pushrod length: With proper pushrod length, the rocker tip should be in the center of the ...

As complicated as engines can be, they are remarkably resilient. When it comes to valvetrain stability, it's critical to get the tolerances correct for the utmost power and longevity. This means ...

When it comes to assembling a host of go-fast engine parts, pushrods are rarely thought of as being anything more than a simple link between the cam and the valves-that is, until one of them breaks or ...
