What is the meaning of LSX

[bigtyme1]

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 Then I thought, Really it was Jay R, my car is really outdated considering most people are using LS2 to LS9.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

Awesome you have the LSX block cool...Well it's a Ls1 ....O..... No really it means the same....... come back, hey come back...... really it's the same

[Stuart Adams]

The engines are so good I thought it stood for Like Sex.

They make them for Charlie's cars

LSX "Lillard Series eXtreme"

[MtotheIKEo]

I usually see it as capitol X means the Iron LSX block

lower case x just denotes a LS series engine LSx

[trapin]

I never understood why the LS2 is referred to as the Gen IV and the LS3 as the Gen V. They're both the same type and design as the LS1 save for a few non-interchangeable parts. I don't know....to me the whole LSX family is the 3rd generation of GM engines. An engine would have to be completely new from the ground up and have little in common with the Gen III for it to be considered a Gen IV.

But then that's just me thinking out loud again. :D

[PonchoJohn]

Me either, since we all know that an LS2 is a 1973 SD-455 Pontiac engine.:unibrow:
