What is the meaning of LSX
 

so I was thinking about adding LS1 to my cowl hood as I paint in a few weeks. Pete offered to help me out with the letters today. Then I thought, Really it was Jay R, my car is really outdated considering most people are using LS2 to LS9. SO jason thought Maybe LSX. is LSX just the iron block motor or is it the name of all the LS motors? Just don't want to lie about what's under the hood.

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" Bore x 4.5" Stroke) and is capable of withstanding 2500 bhp. 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

Also commonly used online when referring to any of the Gen III or IV LS engines instead of listing all possible combinations, LS1, LS2, LS3, LS6, LS7, or LS9. "Do you have an LS(x) in your car"?

Thanks for your help today Pete, I really like your attitude towards building these cars. you really helped me make a few good choices on my paint work.

i agree with van b. although im looking into the "lsx" block, i commonly here all the ls motors refered to as ls"x". im a jason follower, he wont lead you down the wrong path.

LS'X' yes a generic term for LS1-9... but I think your actually asking what does it stand for? Does it have a meaning a origin for the letters?? Why was the first one called a LS1 now commonly known as LSX? Is that what your asking? If so I don't know, maybe some one does???? IMO -LSX would be cool on the hood.

LSX is basicaly the LS family but, it does stand for the GM performance block

Anything I can do to help. You need anything give me a call

i worked on GM cars back in 01 and we called them lsx then so i think it was a trend that grew to them. i say go for it!!!!

lsx is for the ls series of motors and just happens to double as the name of the iron block
