Understanding Valve Springs – Part 2

In this episode of Steve Tech, Steve Morris picks up from the Part 1 video to explain what you need to know for proper valve spring set up and how to prevent spring surge.

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.

Engine Parts: Lifters, Pushrods and Valve Springs

The valvetrain is one of the most critical components in any engine build, be it stock or performance. The lifters, pushrods, rockers and springs must all be strong and stiff enough to handle the loads and RPMs the engine will encounter, and they have to be durable enough to go the distance.

Valvetrain Components

One of the areas that greatly benefits from keeping everything in its proper position is the valvetrain, so let’s look at what can be done to help ensure that.

Round and Round – Valve Timing Events and the Order of Importance

If you’ll recall, in the January issue, we got into the nitty gritty details of what makes a camshaft the “right” camshaft. In this issue, we’ll continue the education. Cam class is back in session! Remember the camshaft makes one complete revolution (360°) while the crankshaft rotates twice (720°) for a complete engine cycle. Camshaft

Keep the Valvetrain on Track

The key to choosing the right valvetrain components is to match the parts to the application. It sounds simple enough, yet many valvetrain component suppliers tell us there are a lot of misconceptions about what kind of parts are best for different kinds of performance applications.

Selecting Pushrods, Rockers and Springs for Your Build

Everybody knows you need the right combination of valvetrain components to maximize an engine’s power potential. The trick is figuring out which components are the “right” ones for a given application. A high revving engine with an aggressive cam needs lightweight rocker arms and stiffer valve springs to keep up with the cam.

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
