Hewes Performance Interview Part 4: Trail and Street Camshaft Choice for 4.6L Jeep Inline Stroker

This video interview with Tony Hewes took place in 2011. Since then, CompCams has changed grind profiles and added new profiles. The legendary 252H camshaft that Tony and I discuss in this video was a mainstay for many engines, including the Jeep 232/258/4.0L engines equipped with distributor ignitions...In 1999, Jeep 4.0L engines began transitioning to distributor-less or "Coil On Plug" (C-O-P) design.
From 2000-2006 all 4.0L engines have C-O-P. These C-O-P engines and PCM controllers require a different camshaft profile than the 252H. The 252H grind will throw a code due to the valve overlap
of this camshaft if used in these model applications.
Consult with the latest CompCams recommendations for 1999-2006 4.0L or strokers based on the C-O-P design...The profile of the 252H (or current equivalent grind) is still highly beneficial to distributor-type (1999-back) 4.0L engines as well as 232 and 258 AMC inline sixes.
