Camshaft Heat Treatment Explained

The shallower dimple in the outer surface shows the hardening properties of the induction hardening process. A diamond tip with a Rockwell C load was used on each.

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. Pushrods can apply as much as 2,000- to 6,000-lb loads between the lobe and roller wheels in a ...

Low Buck DIY: LT1 Adjustable Cam Gear

We chucked up our trusty .350 bit and made our way through the metal, slotting the holes.

When upgrading our LT1 to an LS1-style ignition with the bolt-on kit from EFI Connection, we began installing our camshaft from COMP Cams with the factory cam gear. We found our Top Dead Center and then our Intake Lobe Centerline. To meet our desired 111 degree intake centerline, the cam core was ground at 115 degree lobe separation angle with ... Read More »

Step 3: Roll the cam backward until the gauge reads .50 lift before max lift and take a degree reading from the cam wheel.

Finding the Intake Lobe Centerline is essential to degree a camshaft, and it’s easy. See our Finding Top Dead Center article to learn how to set up the degree wheel. Read More »
