Tech Tips

The fundamental shaft rocker uses a solid shaft, two mounting points, and a solid rocker arm without the need of a stud mounted through the centre; racers can experience benefits in strength and longevity at horsepower levels just 10- to 20-percent above stock. 

We’ve all heard the term, but have you ever wondered what that heat treatment actually looks like, or how it’s done? Well, you are in luck.

Heat-treating a camshaft ensures the lobes will hold up under the demands of the valve train.

Have you ever had a camshaft fail and wondered why?

Check out this video from COMP Cams where they lists the Top Ten Reasons for Camshaft & Lifter Failure.

You don’t need us to tell you that turbochargers are hot. The word on the street is as enticing as it is simplistic. Just stick a turbo on it and you’ll make ridiculous horsepower. We once asked the guru of engine power, Kenny Duttweiler, “How much power can we make with a turbo on a 6.0-liter LS?” His answer was succinct: “How much do you want to make?”

Flex in the valvetrain means less valve lift and less airflow into the cylinder. Could a floppy valvetrain be holding your engine back? This simple test allows you to evaluate your valvetrain with simple tools to gauge its stiffness.

Every component in your engine is held together by fasteners designed for a specific purpose. The quality of those fasteners is your insurance against poor performance and RUD; Rapid Unintended Disassembly.

So, you have a set of pistons that you want to re-ring, but you don't know which rings to order. Here, we go over the options you have for measuring your old rings or ring grooves so JE can get you the rings you need.

While many Dart cylinder heads come assembled with valve springs, sometimes it can be necessary to spec your own set that pair with your camshaft of choice. Here’s how to correctly set up a cylinder head.

When shopping for wires, you’ll find a lot of custom-fit applications that are based on the factory routing of the wires, as well as the boots. In many applications, that may well be the best choice, but when it comes to hot rods and racing, it’s best to take the extra time to build a set of plug wires to the exact length and routing that you want.
