So the engine in your Avalanche is not an actual LSx engine just an LS-architecture engine.
That's not a great explanation technically, but it might help you head in the right direction.
mechanicx's explanation actually makes more sense, now that I think about it.
The LS3 is the engine in the Camaro right now. The LS1 was in the previous F-bodies. It is not "only" a Corvette engine. Of course the LS1 and LS2 were also used in the GTO.
And then there is the L99? LOL and the other weird variants. I'm not sure on GM's exact engine "terminology" other than it can get weird at times.
I actually own a GTO, but I would still consider the true LSx engines to be "Corvette" engines applied to other vehicles
I didn't mean it to sound like it is only used in the Corvette though that's exactly how it sounds now that I look at it...
Yeah, that was how I took it, LOL
