TSP’s all new line of LS3 camshafts are the result of our latest round of engine dyno camshaft development using our state-of-the-art Superflow 902 engine dyno. Using a brand new LS3 crate engine, we started from scratch to build the most powerful LS3 camshafts available in the country.
The Stage 4 235/248 camshaft is the perfect choice for customers wanting the MOST powerful camshaft available that still offers adequate piston-to-valve clearance on a stock short-block. This camshaft is designed for all-out power and shows gains over the stock camshaft beginning at 3,100 RPM. The cam will pull really hard from 4,500 RPM up to the 6,600 RPM HP peak. This camshaft makes 93 flywheel HP more than the factory LS3 camshaft! We recommend a minimum stall speed of 3,600 RPM for this camshaft in auto-equipped vehicles for streetability, but it would benefit at the track from a 4,000+ RPM stall speed. This cam is designed for LS2/L76/LS3 engines using L92/LS3 rectangle port cylinder heads!
