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.

The Issue you will have is the LR4 was still a gen. 3 with 24x computer. The Ly2 is 58X and you would need to purchase a signal converter like the Lingenfelter LPE-L460065397. With the Tac Module, throttle body, injector differences, it’s going to be easiest to swap your original intake manifold to the new engine…it will fit fine. The cam position moved, but you can use a CEI-109089 extension harness. The knock sensors moved to the side of the block so use extension harness LPE-RXLS2-KSRH. Those are the major things you’ll run into
