LS1 Engine Guide: Specs, Features, & More

LS1 Crate Engine

1997-2004 Chevrolet LS6 Engine Ultimate Guide

When people talk about V8’s, especially in the domestic world, the LS series of engines always come to mind. These are relatively inexpensive and robust platforms to build excellent street/strip engines from.

In this article, we’ll be walking through the history of the LS1, some general technical specifications as well as provide some further insight into notable vehicles and/or records that the LS1 has been able to collect over the years.

A Brief History of The LS1:

The LS1 is the spiritual successor to the “small block V8” that GM uses in rear-wheel-drive cars, trucks, and vans. It was introduced in 1995 as the “GEN III” engine and it only shared rod bearings, lifters, and bore spacing with its predecessors (which was in production 1955 until 2003).

Little did GM expect for the LS1 has become a legend in its own time, offering impressive “out of the box” performance for the physically compact package. For those lucky enough to have the LS1 in their cars, the blocks were made of aluminum, while the truck and van versions were cast iron.
