Hey, I am new to this area as I have always been a gas engine nut.
I have a J10 with a 455 olds, and have done plenty of gas engine swaps.

I have a 98 k3500 duelley with a 7.4 vortec and actually runs great, with 89,000 just tired of dumping gas into it.

I found a supplier that has 97-2000 used 6.5 with turbos,(under 150k with "F" vin code for $3600) also complete ecms to do the swap. What will I expect in the swap?...will the transmission bolt up? I know I may have to fab up mounts. I know I will have to change exhaust. Will the radiator and Powersteering pump work from my 7.4? what about A/C? Will I have to find a wiring harness?

Will my gas fuel pump work?

Any and all help will be deeply appreciated.
