TPS C7 LT1 Na Custom Cam

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. 

TPS Motorsports Custom  LT1 VVT-3 camshaft is a great choice for the enthusiast looking for maximum horsepower from their gen 5 LT1. It will have a lope at idle and will require a higher stall speed torque converter for automatics. It does remove the factory AFM/DOD system that deactivates cylinders, but it retains the variable valve timing (VVT) system that allows the engine to advance and retard the cam while the engine is running. This provides a much better power curve since the engine can advance the cam in the lower RPM's for better torque and retard the cam in the upper RPM's for better horsepower. We do recommend using  .660" dual spring kit with & titanium retainers and TPS hardened chromoly pushrods with this camshaft.

Each gen 5 LT1 camshaft offe will require the use of a Comp Cams Phaser limiter kit. The phaser limiter restricts the range of cam timing movement to 20°. This modification provides the necessary valve clearance for serious performance camshafts with tighter lobe separations while still utilizing the benefits of the VVT technology.

We design and test many different camshafts before selecting the camshafts that we offer to our customers. This provides us with a distinct advantage of offering the best power curve possible without sacrificing overall performance, as well as knowing that what we offer is also safe and will not have any piston-to-valve clearance issues. We test our products before we sell them, so you KNOW that you are purchasing a camshaft that is proven!
