LS Engine Spotter’s Guide, Part 2: Matching the Engine to the Vehicle

Junkyard-sourcing a specific LS engine? If you’ve already got the LS or LS-based Vortec engine picked out for your project, this guide will tell you which vehicles came from the factory with it.

It’s also a handy resource to have should you need to grab a specialized bracket or engine-specific parts from that same car, or one like it.

If you’re heading out to the yard just to see what’s available, check out our LS Engine Spotter’s Guide, Part 1: Matching the Vehicle to the Engine post. It contains essentially the same information, only sorted by make and model instead of General Motors RPO codes so you can quickly find out which LS engine came in whatever 1997-and-up GM vehicle you might find.

Make sure you search by RPO code (like LM7, LS1, etc.) to be sure you’ve got the right engine. Many LS-family engines share displacements and are virtually identical even to a keen eye.

Not sure what you’ve got? Check out this article on how to Identify Your LS Engine.

And here is a handy guide to the entire LS engine family.
