I used to work for Predator Motorsports. For a short time we had a guy in Kansas doing the swaps but there were some issues and we started doing them in house. Ryan (Predator owner) is a great guy. His whole family is. Hope you like it. there are tons of things in the diesel world you can do to that monster. have not read all of the posts but what model engine did you go with? hope not a LB7. injector nightmare motor. LLY was a good motor but had over heating issues. LMM and LBZ are the target ones to have. just get rid of the EGR crap and you will be golden.
I went with the 07 LBZ with the allison 1000, 6 speed with EFI live and i did the EGR delete as well.
