So, you’re heading to the junkyard to see what LS engines are available for your next project?

Here’s a handy guide that links specific GM vehicles to the LS-series engine found under each one’s hood.

The GM LS family is quite large, broken into Generation III/IV, so don’t be surprised when you see overlap and unfamiliar RPO codes.

If you’ve already got a specific LS engine in mind, use our LS Engine Spotter’s Guide, Part 2: Matching the Engine to the Vehicle post to find the vehicles it came in.

We’ve also got a post on how to Identify Your LS Engine.

Confused about the LS family tree? Don’t be, check out this 101-style primer.
