TSP's all new line of LS3 camshafts are a result of months 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 power LS3 camshafts available in the country.
The stage 3 LS3 supercharged camshaft is an aggressive camshaft for power applications from 3000+ RPM. This camshaft is designed to make big power gains on boost LS3, LSA, and L92 applications. This camshaft is an ideal choice for max-effort supercharged LS3/LSA engines running 15+ psi of boost! Designed for LS3/LSA M6 cars or automatic cars with 2800 RPM or larger stall torque converters, and the VVT/AFM delete kit (if applicable). We recommend this camshaft for LS3, LSA, or LS2 engines using L92/LS3 rectangle port cylinder heads!
This camshaft was desgined for boost engines, but typical gains of approximately 70 rear wheel horsepower can be seen on stock LS3 cars without a supercharger! These power gains make this camshaft a great option for people wanting to do a camshaft now & add a supercharger later on down the road!
Cam Specs: 231/239, .640"/.629", 115 LSA, 112 ICL
**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 converison kit with a complete, upgraded timing set for those wanting to replace the entire set.**
