TSP Stage 4 "F-35" LS3 N/A Camshaft

For those ready to take their LS3-powered ride to the next level, the TSP Stage 4 "F-35" Camshaft (Part Number: TSP-235248-111-3B) is a game-changer. Designed for maximum power without compromising piston-to-valve clearance on a stock short-block, this camshaft is the ultimate upgrade for performance enthusiasts who demand more from their engines.

Performance Highlights

The Stage 4 camshaft features aggressive specs with a 235/248 duration and .649/.615 lift, providing a significant boost in horsepower and torque. You’ll start feeling the gains over the factory LS3 cam as early as 3,100 RPM, with the real power kicking in from 4,500 RPM all the way to a peak at 6,600 RPM. Expect an impressive increase of 93 flywheel horsepower compared to the stock setup, making it a solid choice for those looking to dominate both the streets and the track.

Installation Notes

For optimal performance, we recommend pairing this camshaft with a minimum stall speed of 3,600 RPM in automatic vehicles. If you're hitting the track, consider a stall speed of 4,000 RPM or higher to fully utilize the cam's capabilities. This cam is specifically designed for LS2, L76, and LS3 engines equipped with L92/LS3 rectangular port cylinder heads.
