This is not the answer to your question, but you may find it this to be some interesting reading while you wait.

Maybe I'm losing my marbles, but I don't think that it is true that the LS1 is "almost identical" to the LT4.
Wasn't the LT4 based on the LT1 (diffferent heads, cams, etc.), while the LS1 was a totally new engine for the C5?

The L has been used to designate the Generals engine RPOs for at least 40+ years. You may have heard of L71, L79, L88, LS5. I have never heard what the L, T, or S letters may stand for though.

Maybe I should have asked Dave Hill that question when I was at the GM Corvette Tech Center show instead of asking him about quality. He probably would have given me an answer instead of blowing me off about quality. Nice to meet another person full of themselves. Can't have too many of them. Then watching him put a foot on someones tire (without asking)to sign an autograph was even more irritating!
