LS3 Stage 3 Supercharged Camshaft


TSP LS3 Stage 3 Supercharged Cam Specs: 231/239, .640"/.629", 115 LSA, 112 ICL

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 designed 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 down the road!

  • Engines best suited for: 6.0, 6.2 (Equipped with rectangular port heads)
  • Desired Compression ratio for cam: 10.0:1+
  • Recommended Springs Required: TSP/PAC Dual .660 Valve Springs
  • Aftermarket Stall Converter Required: Yes 2800+
  • Upgraded Rear Gear Required: No
  • Operating RPM Range: 2200-6800
  • Estimated Power Increase: 70+
  • Drivability: Will drive great, possible slight bucking for manuals but overall can be daily driven once properly tuned,

**This camshaft is only offered in a 3-bolt design, so if you have a single-bolt factory camshaft you will need to purchase a 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.**
