Extensive CNC and dyno testing has resulted in one of the most powerful LT-based cylinder heads available!

The gen 5 LT1 engine utilizes Variable Valve Timing (VVT) controlled via a cam phaser. A cam phaser is a computer-controlled cam gear that automatically optimizes camshaft timing based on the current engine RPM. While this technology provides tremendous efficiency benefits, it presents a challenge when designing performance cams due to the wide range of valve timing movement and constantly changing piston-to-valve clearance. With the help of Texas Speed’s Superflow 902 engine dyno, we are able to custom-design camshafts and phaser tuning tables to allow our gen 5 LT1 customers the ability to purchase the ultimate in Gen 5 LT performance camshafts! Thanks to the Superflow 902 dyno, Texas Speed is the only company that currently offers a VVT camshaft with a phaser table included to properly tune the camshaft phaser!

This package will require DOD delete kit # 25-LT1DODDEL-KIT since all of our camshafts do not utilize the factory DOD/AFM system.
