I used a donor engine (5.3L Chevy Vortec V8 from an 03 Tahoe) and tranny (2wd from an 01 1500 pickup). . . the transmission adapter requires a 2wd trans, come to find out, but the truck still runs 4wd. We used custom exhaust, Autometer gauges, lots of custom engine bay fab and a honking radiator, kept the Chevy computer and port. I'll take a pic over the weekend of the engine bay if you like.
