TSP Stage 4 "F-35" LS3 N/A Cam Specs: 235/248 .649/615 111 LSA, 109.5 ICL

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!

**This camshaft is only offered in a 3-bolt design, so if you have a single-bolt factory camshaft you will need to purchase the three-bolt conversion kit that will supply the correct 4x upper timing gear to supply the correct camshaft position signal, as well as the ARP camshaft bolt kit that will supply the three required bolts.  We also offer the conversion kit with a complete, upgraded timing set for those wanting to replace the entire set.**
