The Kelford Cams range of catalogue cams for LS series engines come from many years of design, development and testing. We believe that we have the best lobe designs in the industry for these engines. Our profiles feature more duration at .200" (for the same at .050") while retaining the desired level of valve-train control. This results in greater power over a wider RPM range for our customers.

All of our camshafts are made using three-bolt cores, however most profiles are available as a single-bolt cam upon request; please specify your requirement when ordering.

Custom camshafts are also available, either designed for your application, or manufactured to your specifications.
