Description

A suped up 5.3 that is ready and willing to deliver

Continuing the tradition of great small-block V-8 engines, the 5.3L LS engine has been one of the most popular we've ever built. It's been installed in millions of GM-built pickups, work trucks, vans, and SUV's. But, leave it to the GM Performance Parts engineers to go one step further and upgrade the 5.3L LS. The result is a High Output 5.3 that is just as capable serving as a workhorse - it's just a little bit more fun.

We started with the base engine - 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 our 5.3 High Output crate engine so special is that our engineers added a GM Performance Parts custom cam and Grafal-coated pistons. With these simple upgrades, the 5.3 HO kicks out 327 horsepower and 347 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.

This crate engine is a " Drop-in" replacement for the 1999 - 2006 LM7 5.3L V8 found in the 1999-2006 C&K full size trucks.
