I have a chance to buy a new crate motor. It's the L98. Are these any good? I've never heard of this motor. Says it's a LSX. Any info would be great. Thanks!

L98 is the TPI 350 from the third gens and early C4's. They make awesome torque, but I wouldn't unless it was a smoking deal...not an LSX either.

If this is the case, then while technically not LSX, it's an iron block, subtle differences version of an LS2 and almost everything is interchangeable.

good info, makes me think we should have a list made into a sticky of all the relevant GM engines, codes, and applications.

I dislike the L76 because of DoD, and I dislike the L99 for the same reason.
However, the L98 sounds like a good motor. Any LSx without variable displacement is a good LSx.
And the old 5.7L TPI L98 was a great motor in it's day, tons of torque and enough power to finally bring some performance back to stock Corvettes and F-bodies in the mid-late '80s.

I have an '86 C4 with an L98 + Doug Nash 4+3 transmission. I'm pulling it out to put in an LS2. The L98 and tranny have about 79k miles on them and run great. Shoot me a PM if you're interested.
