TSP Gen 5 L83 5.3L (Version 2) Stage 1 Camshaft:

212/224 .610"/.610" 112 LSA, 108ICL w/ 10% Fuel Lobe

The Texas Speed & Performance L83V2-Stg1 camshaft is our newest version of our already popular L83 camshaft lineup. We were able to redesign the lobes for less lift and more power than our previous version. Not only will the new version be easier on the valve springs but the valvetrain noise will be much quieter too! This camshaft is a great choice for the enthusiast looking for an additional bump in horsepower without sacrificing any drivability. Factory torque converter friendly! It does not retain the factory AFM/DOD functionality that deactivates cylinders, so a DOD/AFM delete kit will be needed.

• Engines best suited for: Gen V 5.3L L83

• Desired Compression ratio for cam: Stock

• Recommended Springs Required: TSP dual .660 spring kit

• Aftermarket Stall Converter Required: No. Factory converter friendly!

• Upgraded Rear Gear Required: No

218/230 .610"/.610" 113 LSA, 109ICL w/ 10% Fuel Lobe

The Texas Speed & Performance L83V2-Stg2 camshaft is our newest version of our already popular L83 camshaft lineup. We were able to redesign the lobes for less lift and more power than our previous version. Not only will the new version be easier on the valve springs but the valvetrain noise will be much quieter too! This camshaft is a great choice for the enthusiast looking for a great bump in horsepower, good drivability, and noticeable chop. Due to the nature of this cam it will require an aftermarket torque converter. It does not retain the factory AFM/DOD functionality that deactivates cylinders, so a DOD/AFM delete kit will be needed.
