Additional Information

The Gen V LT platform utilizes Variable Valve Timing (VVT), which can complicate camshaft design due to changing valve timing and piston-to-valve clearance. This package is built around a Non-VVT 3-bolt camshaft for customers looking for a more traditional high-performance camshaft setup.

This package was developed with help from Texas Speed’s SuperFlow 902 engine dyno, resulting in one of the most powerful LT-based cylinder head and cam combinations available.
