| 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 235/239 camshaft uses a all new proprietary intake lobe designed to offer extra duration while maintaining proper piston-to-valve clearance for stock piston LS3/ L92 engines. The result of these lobe design changes is a camshaft that makes more power than our popular 231/236 camshaft while still maintaining adequate p/v clearance! (check dyno sheet above) LS3 computers can easily be tuned to drive great with this camshaft with some bucking below 1500 RPM. Automatic-equipped cars will require a torque converter with a minimum stall speed of 2,800 RPM. We recommend this camshaft for LS3 or LS2 engines using L92/LS3 rectangle port cylinder heads!
Specs: 235/239 .627"/624" 112 LSA
**The factory LS3 camshaft uses a single-bolt cam design, which means one bolt holds the upper timing sprocket on the camshaft. For LS3 vehicles, you must convert to the three-bolt camshaft design that the 1997-2006 LS-based vehicles use. The three-bolt conversion kit 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.** |
