Looking for a late model LS engine that has a little thump from the camshaft? This 525 hp LS3 with the aggressive ASA performance cam will fill the bill. With a tight lobe separation of 110-degrees and 0.525 in. of lift on both the intake and exhaust—along with 226-degree duration on the intake and 236-degree duration on the exhaust measured at 0.050 in.—this cam produces superior throttle response and great top end power. Chevrolet Performance also offers a complete ECM/Wiring Harness Kit programmed and calibrated to match this camshaft for proven drivability and performance. The 525 hp LS3 is the perfect crate engine for those desiring a “bumpy” camshaft idle for a drop-in package.
