Whatever your decision, I'd shy away from Holley. I have one of their TBI systems, and I have been pretty happy with it, but, their tech support is next to non-existent. You are pretty much on your own with programming and such.

If I were doing it again, I'd go with an Edelbrock TPI system. Much easier programming, better support and a better design too.

Another thing: If you just pull a GM system, you are most likely going to need a stand alone ECM or find a way to reflash or re-prom it. Cam profiles, intake design, valve sizes, and other factors will have an effect on the way the system works on another engine. Close isn't quite good enough with fuel injection.

BTW, plenty of TBI harnesses available Google TBI wiring harness. Good luck.
