Your camshaft and timing system quietly keep your engine in perfect rhythm — until they don’t. From worn lobes to failing phasers, small issues can snowball into major repairs if ignored. Knowing the ...

If there's an elusive animal in the amateur performance world, then degreeing a cam is it. Few know how to do it, and even fewer understand the benefits. If you're following our 347 build from the ...

This diagram shows the major cam events through one full cylinder cycle (two crank revolutions or 720 degrees), beginning at TDC firing. The exhaust lobe and valvetrain is closer to the front, and ...

Crankshaft and camshaft sensors are the unsung heroes of engine performance, feeding precise timing data to your ECU for spark and fuel control. When their signals drift out of sync, you can face ...

We must first understand what each of these two systems does for a car. They both serve the same purpose, which is to coordinate the movement of the crankshaft as well as the camshaft(s) so that the ...

Upgrading your engine from a flat-tappet valvetrain to roller comes with a lot of advantages—mainly more power and radically reducing the chances of wiping a camshaft lobe—but it also requires a few ...

A cam phaser is a sprocket which adjusts the position of an engine’s camshaft in relation to its crankshaft and is tuned with a computer-controlled servo. Camshafts control the timing of engine intake ...
