Supercharged LT Build

[vannatta20]

Hey guys I have been on the site for a long time and did a thread, 5.3 swap the easy way and I can not believe it has 226000 views! Super cool. I now have a square body and love it. I specialize in LT conversions as a living now. I hope I can help anyone that needs help to get these up and running. The LT's are a bit different but I have done over 50 conversions and tons of harnesses. I have these figured out quite nice. Here is my build. I found it on craigslist in Las Vegas. I feel in love with the patina and it being a cheyenne. The truck ran but not well with its small block chevy. It had bad compression.

I purchased a L83 off of Ebay for 1700$ shipped. Next I bought a 6L80e as well from ebay for 800$. I reworked the harness that shipped with the engine. I decided I need experience in tuning these with cam swaps and got a stage 2 cam from texas speed. I also changed the 5.3 intake from a truck to a LT1. It looks very cool. This is to be my test bed to experiment. I have heard the debate that the LT's must run 70+psi of fuel pressure. I have been running 57psi LS style systems with no issues but decided to install a Gen V LT1 fuel pump with variable fuel pressure. I used a boyds welding tank and dropped the sucker in. Tuning has been quite frustrating since these are very different in they way the computer controls engine. It is a torque based controller and are much more finicky. With lots and lots of testing and tuning I have it very nice. I have put about 3000 miles on it and have done multiple road trips. I came across a deal on a LT4 supercharger and decided to take the plunge into unknown territory and see if I could get it to work. Good news it is it fit and I even got it tuned very nice as well. It is a beast now! Super cool to here the blower whine.
