Set of 16 7.85" TSP 3/8" Hardened Chromemoly Pushrods (25-7850-1)
Comp Cams Phaser Limiter Kit (4-5456)
Texas Speed is one of very few companies that is able to test and properly develop Gen 5 L83 camshafts using the camshaft phaser. As a result, it is very important that we do not release the entire specs of each 5.3L L83 camshaft. If you have additional questions about sizes & recommended use please give us a call!
The +32% fuel lobes are recommended for any setup that is running a power-adder. The +32% fuel lobe does require a lash cap with it, so make sure it is installed during the camshaft installation! You can include the lash cap in the appropriate drop-down menu if you are purchasing a +32% fuel lobe camshaft.
The TSP Gen 5 L83 camshafts are custom designed for applications where the AFM lifters are being removed. By removing the AFM lifters, we are able to run lobes that offer better power and performance. You will have to purchase our TSP DOD Delete Kit for any of our L83 cams, which can be configuredhere. Our DOD Delete Kit will include the following items:
Eight New LS7-style Lifters (Set of 16 available for additional cost)
Set of (4) LS2 Lifter Trays
GM Head Gaskets
Your Choice of GM Head Bolts or ARP Head Bolt/Stud Kit
DOD Plugs (Will NOT require the use of the Katech valley cover!)
GM Balancer Bolt
GM VVT Camshaft Bolt
All TSP Gen 5 L83 camshafts require the use of the Comp Cams Phaser kit, which is included in L83 Cam Package. We do recommend replacing the factory trunion in your GM rocker arms with the Comp Cams trunion upgrade kit!
Each Gen 5 L83 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.
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!
We do offer the Katech AFM delete valley cover for those customers that prefer to replace the cover instead of using our DOD delete plugs that install in the DOD stacks in the valley of the block. You can select the optional cover in the drop-down menus below.
