Fits On/Installation Notes:

Based on the tough, proven, and dependable 5.3L engine, it's the same long-lived production engine that you'll find in our award winning full-sized truck and SUV line. The stock 5.3 offers a dependable 295 horsepower and 325 lb.-ft. of torque from the 96mm bore by 92mm stroke engine design.

What makes the 5.3 High Output crate engine so special is that the GM engineers have added a GM Performance Parts custom cam and Grafal-coated pistons. With these simple upgrades, the 5.3 HO kicks out 332 horsepower and 352 lb.-ft. of torque. And, just like the stock 5.3, the 5.3 HO is capable of thousands of miles of dependable service while returning outstanding fuel mileage, thanks to the superior design of the LS Family of engines.
