Texas Speed (TSP) Stage 3 LS3 Supercharged Camshaft (25-TSPLS3Stg3): 231/239 .640"/.629" 115LSA These camshafts have a 3-bolt timing gear pattern and will require a 3 bolt conversion kit if your OE LS3 camshaft is single bolt. Single bolt versions of the cam are available by request, but we highly recommend upgrading to the three bolt conversion.
Texas Speed and Performance's LS3 line of cams are known for consistent power gains and are an excellent selection for GM LS3 6.2L engine applications. The "supercharged" line of cams are specifically designed for forced induction combinations and are optimized for positive displacement style superchargers such as the factory ZL1/LSA supercharger or aftermarket brands such as Magnuson or Whipple.
From Texas Speed:
"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!"
