OE Optimizer ™ Camshaft used in today's production 6.5L engines. This hydraulic roller bump stick is backwards compatible with 6.2L engines and is the absolute best quality unit available for replacement use.
Compatible with 6.2L and all 6.5L engines including the P400 6.5L.
The production P400 uses this same cam, verified from actual P400 engines taken apart and measured on cam profiling tooling to compare, and all units bear the same numbers. Same cam despite what some others have falsely claimed to earn a premium for the standard cam.
