Genuine GM Parts 12583623 - L33 5.3L HO Camshaft

The GM L33 High Output camshaft provides excellent torque and power, originally rated by GM at 310-HP and 335-FT/LBS of Torque. Compared to the base LM7 5.3L, this cam has a little more duration and slightly more lift. Excellent camshaft for DOD conversions or LS engine rebuilds desiring to use a stock GM camshaft. We recommend the use of the LS6 spring upgrade from Scoggin Dickey and Chevrolet Performance - Part # 12499224. Will work with the stock 5.3L valve springs. A simple install for 5.3 owners for increased performance, power, and torque. This is a 3-Bolt style camshaft.
