Interesting thread--I'm putting 5.3 LS1 from a 05 Tahoe in, not there but working on it. My concern has been the electronics but there does seem to be many different suppliers of wiring-just don't know which might be better than another. One thing I've heard from other places that HP is only ltd by imagination and money!
Mine has alot of miles but inside valve cover it looks like new and very well kept. Guess I'll pull it down and check it to be sure. Should prove to be an interesting experience but hope driveability and reasonable fuel economy to be on the positive side in the end. If anyone has used the Holley system I would like to hear how that has worked out as to performance and expense???
