Well I did a TBI on a 194 inline in a 63 nova just took it all off a 4.3 v6 tbi, sensors, ecm made the harness.Need to add a EFI pump and a return EFI line (kit from jegs or summit$40). Have all the pin outs for the gm ecm and wire diagrams that I made cutting out stuff like the EGR, if you would like to see them let me know. Took me 2 months but most of it was reading and talking to others on how to do it. I did it for the nitrous as my turbo dreams were shattered with the shock towers in the way but with a truck I think you may be ok I know there is a turbo manifold on ebay now and there is the place that makes the 3.8sc manifold.
hope this helps
