TSP Turbo LT1/LT4 3-Bolt - No VVT

Take your Gen 5 LT1/LT4 engine to the next level with the TSP 6.2L LT1/LT4/L86 3-Bolt Camshaft featuring a complete VVT delete. Designed using Texas Speed’s in-house Superflow 902 engine dyno, this camshaft delivers the ultimate power curve without sacrificing reliability. Perfect for turbocharged builds, it features a new 3-bolt design that eliminates the variable valve timing system without the need for a phaser limiter — ensuring accuracy, simplicity, and performance.

Performance & Compatibility

Built for enthusiasts chasing maximum horsepower, this camshaft provides a noticeable lope at idle and will require a higher stall speed torque converter in automatic applications. It does not retain factory AFM/DOD or VVT functionality, so appropriate delete kits are required. This design allows for improved cam phasing—maximizing torque down low and horsepower up high. For best results, pair with TSP’s .660" dual spring kit featuring PAC springs and titanium retainers, along with TSP hardened chromoly pushrods.

Every TSP LT1 camshaft is rigorously tested on a SuperFlow 902 engine dyno using an otherwise stock 6.2L LT1 engine. This ensures optimal performance and piston-to-valve clearance safety. With TSP, you're not just buying a cam—you’re investing in proven horsepower gains and reliability.
