Not intending to send you away from Club Hot Rod, I would recommend you visit the LS1Tech.com Conversions and Hybrids Forum. I did my LS1 Swap into my Studebaker 10 years ago and the folks there were extremely helpful. Much has happened since then to make these installations easier and the folks there are on top of it. They have a number of "Stickys" at the top of the forum with a wealth of information. Read read read.
