Pushrods: What You Need to Know

In this episode of Steve Tech, Steve Morris of Steve Morris Engines talks about pushrods and what attributes you want to see in pushrods and what the effect of pushrods are in the valvetrain.

Camshaft Tech with COMP Cams’ Billy Godbold

We caught up with Billy Godbold to discuss all things camshaft, from common misconceptions to proper camshaft selection to firing order and much more.

Don’t Drop That Valve

In this episode of Steve Tech, Steve Morris tells you more about your engine’s valves and lash caps.

QualCast Heavy-Duty and Diesel Valvetrain Kits

These kits include all the parts you need to complete your cylinder head build in one box.

Valves, Rocker Arms & Pushrods

Just keep in mind your application, your rpm range and horsepower goals. The valvetrain puzzle falls into place from there.

What to Consider for Valvetrain Selection

Valvetrain components all work in conjunction to allow air or the air/fuel mixture in and exhaust gases out of the engine, and the selection process for the proper parts can be complex.

Professional Secrets to Selecting Valve Springs

Valve springs play an essential role in controlling the breathing in internal combustion engines. The valves are mechanically opened by a camshaft, with the help of the valve lifters or tappets, and closed by the valve springs. But valve springs perform one of the most the critical functions: lifting the weight of the valve. Valve

Rocker Arms – Connecting Up Your Valve Train

Understanding how rocker arms work The rocker arms in an engine have one simple but very important function: transferring the opening and closing events from the camshaft to the valves. Well, we all SAY it’s simple, but is it? Questions about what works best are still asked by even the most seasoned professional. With all

Valves and Valve Seats – There’s More than Meets the Eye

The valves and seats in an internal combustion engine play a central role in engine breathing, compression, performance and longevity. It doesn’t matter if an engine has two, three, four or even five valves per cylinder or if the engine is gas or diesel because the valves all do the same thing: they open and close to allow air into the cylinders and exhaust to exit the cylinders.

Form, Fit & Function – Valvetrain Components Must Work in Harmony

The upper valvetrain is one of the most critical components in an engine build, so it’s essential you choose the right parts for the application and install them correctly. Here are some suggestions for getting things right: DON’T USE “STANDARD” LENGTH PUSHRODS Many variables can affect the length of the pushrods that are required to

Pick-a-Part: Selecting Valvetrain Components for a Performance Build

Selecting the right components to make a race-worthy valvetrain is crucial to assembling an engine that will last – and win. The pushrods, rockers and valve springs must be able to handle all of the stresses of the camshaft rotating with high spring pressures and with huge lift. As we all know, weakness in any
