The Texas Speed & Performance L83TR-2 camshaft is a great choice for the enthusiast looking for an additional jump in horsepower without sacrificing much driveability. It will have a slight lope at idle and drive similar to stock. 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 the TSP .660" dual spring kit with PAC springs and titanium retainers and TSP hardened chromoly pushrods with this camshaft.
Each gen 5 L83 camshaft Texas Speed offers will require the use of a phaser limiter kit. The phaser limiter restricts the range of cam timing movement. 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 do recommend the +32% fuel lobe for any vehicles that are using a power-adder. The +32% fuel lobe does require a lash cap, so please make sure that you install one during the camshaft installation! You can select one in the drop-down menu.
All of our TSP L83 camshafts were designed on our SuperFlow 902 engine dyno using an otherwise stock 5.3L L83 engine. 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!
