I meant to mention... most likely, the source for LS1 parts that I know of is Billy Grahm's Camaro/Firebird Salvage... I have dealt with them before for OTHER Firebird parts during my Trans Am craze (three WS6 drop top's and one non-WS6 drop top)... anyway, I know they will have the motor and trans... as well as the computer... the retro harness like I said can be bought through Jeg's for $499. Just wanted to make sure I mentioned this info. I'll check back later!
