it doesn't show that it has wiring or computer. Is it even feasible to think this might be a good idea for my CC dually?
I already have a 94 4L80E, any chance that would be compatible with the correct computer for the engine?

96-up vortec series motor

and yes was offered with 4l80 factory .

I my self tend to not like the vortec series in that year range style. at least in sbc form .

I had a vortec 7.4 in my 98 dually with a stick, before I put the cummins in it. Bloody brutal on fuel. That's actually why I pulled it for the 12v. Fill up every 3rd day. Forget that crap.

I had a 96 dually C30 with that combo in it...11.5 everyday, 13 highway, and 8.5-9 towing 8K

The stock 98-00 harness would work with same PCM, or rewire the PCM plugs to a 2002 LS1b 0411 PCM.
