I read a few threads and saw a few pictures of supercharged M113 swaps.

I am specifically curious about the 4.3 because I would want to keep my 6 spd. It appears the torque that the 4.3 has is right on the edge of what the 6 spd will handle.

I did a V6 to V8 conversion about 11 years ago. I pulled the throttle body injected 4.3 V6 from my 1991 4X4 5 spd standard cab short box S10 and installed a.030 over Tuned Port Injected 350 from an 89 IROC Camaro.

The difficulties with that swap were finding the right clutch plate with 10 splines that would work with the NV3500 5spd and Camaro flywheel, the T5 Camaro trans has 18 splines, and the other was the wiring and defeating the VATS. I was converting from Throttle Body to Multi port, and from a MAP sensor to MAF sensor with the associated relays. The wiring took about 6 weeks to sort out working on it a few hours every day. Needed a custom built oil pan to clear the front diff as I didn't want to do a body lift. Truck basically looks stock.... until I start it. I still have it, but it just sits now.

I was thinking that since the M112 and M113 share the same architecture, it would probably be a pretty straight forward swap. Just have to figure out the wiring.
