Summit Racing Big Block Chevy Hydraulic Roller Camshafts

Made in the USA from billet bearing steel and finished on Landis grinders, the cams have a 4/7 firing order.

Summit Racing Pro Hemi Camshafts

The Pro Hemi Camshafts are precision ground in the USA from high-quality bearing steel billet cores and finished on modern Landis CNC grinders.

Steve Morris Engines builds engines for Manny Alvarez of HPP Racing. Manny was recently telling Steve that one of his engines was breaking valvetrain components after just a couple runs. Steve had built him a different engine that had been super fast and super reliable, so Steve asked Manny to send the other engine back

Understanding Camshafts – Part 3 (Cam Design)

Now that Steve has run through lobe shapes and cam cores, you’re ready to put it all together in order to understand what goes into designing a custom camshaft, and the reasons behind certain decisions. If you missed Part 1 or Part 2, view them at the links.

Understanding Camshafts – Part 2 (Cam Cores)

There’s a lot of detailed information that comes with camshaft selection, but core size is one of the more important aspects as it dictates several other specifications of the cam itself. Steve explains in this episode. Stay tuned for the final Part 3 video on camshafts. If you missed Part 1, click here.

Understanding Camshafts – Part 1 (Lobe Shape)

The camshaft is to an engine as a conductor is to an orchestra. A lot rides on having the proper camshaft selected for your engine application. In Part 1 of this Steve Tech on camshafts, Steve Morris discusses lobe shape and the importance of choosing the right shape for your expected performance goals. Stay tuned

Camshaft Art and Science – You Get Out What You Put In

The most misunderstood component of an engine is the camshaft. Selecting a camshaft and understanding its profile and design can be a “black art” as most of what a cam profile controls is invisible – air. Yet, the camshaft has a major impact on engine performance.

There’s No Simple Formula to Choosing the Perfect Camshaft

The camshaft design affects valve timing, compression and the engine’s ability to breathe. From pistons to manifolds, valve grind, piston pin offset, rod length, etc. Once the camshaft has been tabbed correctly for the application, the rest of the build can focus off that selection.
