The Starck Performance Cam Kit

Our own custom-ground HEMI cam package — developed and proven on our own cars. It wakes up the 5.7 and 6.4 with a mean, lopey idle and real power where you feel it, backed by the springs, pushrods, lifters, and the tune to run it right. Run it on its own, or as the heart of a Stage 3 build.
