Is the LS4 a "LSX" I was just wondering what is a LSX? I seen a bunch of photo's with different LS powered cars running the LSX badge..Is our engine part of that group?
Or is it something else. Just a curiosity to know the terminoligy!

Yes the LS4 is part of the LSx family and shares parts with the others.
But to confuse everyone there is an LSX 7L engine, that's in a few special edition products.
EDIT: I take that back about the LSX it's an 'iron racing block.'

LSX
At the 2006 SEMA show, GM Performance Parts introduced the LSX engine, an all-new cast-iron racing block based on the LS7 engine. It was designed with help from drag racing legend Warren Johnson. It offers displacements ranging from 364 cubic inches to 511 cubic inches (4.25 in (108 mm) Bore x 4.5 in (114.3 mm) Stroke) and is capable of withstanding 2,500 bhp (1,900 kW). This block incorporates two extra rows of head-bolt holes per bank for increased clamping capacity. The six bolt steel main caps are the same ones used on the LS7 engine. The engine debuted at the auto show in a customized 1969 Camaro owned by Reggie Jackson. The LSX will be available starting the second quarter of 2007, set to be available in authorized dealerships and retailers on March 31, 2007.

The x stands for LS1, LS2, LS3, LS4, LS6, LS7, LS9, LSA for the most part. You can throw the Gen III and IV truck blocks into this category as well. Even the L76, L92, L99, L33, ect. There's alot of LSx motors out there. Basically if GM is putting a V8 in it now, it's a LSx type.

Think of the x as a variable, where x = 1, 2, 3, 4, 6, or 7, and it makes more sense (at least to me). LSx denotes any of the modern LS engines, regardless of the version.
