What is an LS Engine?

The LS engine series, developed by General Motors (GM), was introduced in 1997 as part of the company's small-block V8 family. These engines combine modern engineering with the simplicity and durability of traditional pushrod designs. The result is an engine that delivers outstanding power-to-weight ratios and adaptability for various applications.

Why Choose an LS Engine?

Compact and Lightweight Design

The LS engine’s aluminum block and pushrod architecture make it compact and lightweight. This allows for easy installation in a wide range of vehicles, from muscle cars to trucks and even imports.

High Performance

With robust internals and advanced features like cathedral port heads and cross-bolted main caps, LS engines deliver impressive horsepower and torque straight from the factory. They’re also highly receptive to modifications like forced induction and upgraded camshafts.

Affordability and Availability

As GM produced millions of LS engines, they’re widely available and reasonably priced. A thriving aftermarket ecosystem ensures you’ll find parts and support for any project.
