A few of you have asked me about the “LS6” block versus the “LS1” block. Very simply, we could not supply enough LS1 blocks back in, as I recall, 1999. Thus, the corp (GM) made the commitment to build another plant to produce more V8 ‘blocks’ — the difference is that if your block is bright silver (finished edges) it’s a St. Catherines Block. If it’s a bit darker gray, then it’s what some call the “LS6” block — built in Mexico — the difference is that both blocks are LS1/LS6– same design — but my hat is off to the people within GM Powertrain — they made the decision to build the additional plant for additional V8 engines — the rumor was that we’d only get a V6 engine for model years 2001 and 2002 as I recall – and the team made the call to ‘kill the car’ at the end of 1999 production as we could not profitably sell Camaros with only V6 engines — the program would once again start losing money as we did not make anything (…in fact we lost money on all but ultra-loaded V6 Camaros and Firebirds) — and the team won. Thus, the ‘story’ of the “LS6” rumored block……..
