TSP's all-new line of LS3 camshafts are the result of our latest round 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 powerful LS3 camshafts available in the country. Texas Speed & Performance continues to test and develop new designs to make sure that our customers have the BEST camshafts available! - - - 229/244 .629"/615" 112 LSA, 109 ICL
