Additional Information

The Gen V LT platform utilizes Variable Valve Timing (VVT), which presents challenges when designing high-performance camshafts due to constantly changing valve timing and piston-to-valve clearance. By converting to a non-VVT setup, this package simplifies tuning and maximizes performance potential for aggressive builds.

This package was developed using Texas Speed’s SuperFlow 902 engine dyno, ensuring optimal power curves and proven performance results.
