I was checking out the Mega Squirt system but for the price of $500 (computer, MS to GM747 ecm, wideband o2) its my absolute last resort. I really would like to make this a true junkyard TBI setup.

Ive been searching the local u-pull-it yard and online thinking that GM would of put a TBI setup on the 3.8L or similar engine before they went to a MPI (or whatever they call it) setup. A 3.8L would be have been alot closer of a match for the 235 (3.9L)
