Hello all,

i have a '03 silverado ss and frequent silveradoss.com and performancetrucks.net i just heard about this site, so i thought i would stop over for some good reading. i do have one question that may seem to be very stupid to most of you. I havn't been "keeping up" on GM engines and there codes, so i was wondering if someone could explain to me what all the codes mean? example: LS6, LS1, LT1, etc.? what are the differences and such with each motor? I have a 6.0L, is that a LS1?
