Description

The LM7 is a 5.3L, Gen. 3 small block engine used in GM trucks between 1999 and 2007. For marketing purposes, it was also known as the Vortec 5300. The information listed here is for the stock LM7 engine.

 

Mechanically similar, General Motors’ LS and LS-based Vortec engines wound up on almost every branch of the GM family tree: Chevy, Pontiac, GMC, Cadillac, Buick—heck, even Saab, Hummer, and Isuzu got some LS love.

 

Since LS and Vortec engines are so common, they’ve become the go-to performance and swap engines of the modern era.

 

These motors are capable of making a lot of horsepower, and respond well to upgrades like turbos, superchargers, high-flow cylinder heads, intake systems, cams, and nitrous oxide.
