Texas Speed & Performance 6.2L LT1/LT4/L86 VVT Camshafts

The Texas Speed & Performance LT1 VVT-SV camshaft is a great choice for the enthusiast looking for an additional jump in horsepower without sacrificing hardly any driveability. It will have a slight lope at idle but nothing too aggressive.  This is the perfect camshaft for those wanting to retain the stock torque converter in their automatic-equipped LT1.  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 our TSP .660" dual spring kit with PAC springs & titanium retainers and TSP hardened chromoly pushrods with this camshaft.

Cam Specs: 223/227, .635"/.635", 116 LSA

Each gen 5 LT1 camshaft Texas Speed offers 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.

The Texas Speed & Performance LT1 VVT-2 camshaft is a great choice for the enthusiast looking for an additional jump in horsepower.y. It will have a nice 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 the +32% fuel lobe for any power-adder applications.  The +32% fuel lobe will require the use of a lash cap, so please make sure that you install one during the camshaft installation!  You can select the optional lash cap in the drop down menu.  WE DO NOT CHARGE EXTRA FOR OUR +32% FUEL LOBE!
