Texas Speed Stage 4 LS3 N/A Camshaft

The Stage 4 camshaft is a great mid-duration camshaft for power applications from 3000 RPM+. This camshaft is an excellent choice for customers wanting more power than our 231/246 yet still wanting to retain nice streetability. Automatic-equipped vehicles will require a minimum stall speed torque converter of 3,600 RPM. We recommend this camshaft for LS3 or LS2 engines using L92/LS3 rectangle port cylinder heads!

Note: Valve Springs Required Use TSP or PAC .660 Dual Valve Springs.

Notice: 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.
