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’re working on a definitive LS resource that will answer your questions—sit tight, it’ll be ready soon.

  2. Robert Learned says:

    What is the bore & stroke for LS engines

    • The bore ranges from 3.780 to 4.125. The stroke ranges from 3.287 to 4 inch. The common families are 4.8, 5.3, 5.7, 6.0, 6.2, and 7.0.

  3. What years are the splits on the 24-58 tooth reluctors

    • OnAllCylinders Staff says:

      Hey Rob, we asked our LS gurus your question and here’s what they said:

      Gen. 3 engines could be found in cars up until 2005 and most trucks as late as 2007 (LM7, L59, L33, LQ4, LQ9) and were 24X.

      The Gen. 4 engines could be found in the LS2 Corvette, GTO, and LS4 powered FWD cars as early as 2005, but remained 24X equipped.

      By 2006, the Corvette and CTS-V had gone 58X, but the LS2 powered GTO, TBSS, SSR (along with LS4 powered FWD cars) and LH6 powered SUV’s remained 24X.

      By 2007, all Gen. 4 powered cars and trucks were 58X.

      Hope this helps!
