98 7.4 vortec to 6.5 turbo swap

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.

I have been down this road my signiture truck started life as a k3500 5.7 gas its now a tricked out 6.5 looks factory stock while except the after cooler remote mounted fsd the after market air cleaner, wiring wish can not tell it was not a 6.5 all its life if you like e-mail me privately i would be glad to talk to you on the phone to help answer your questions,

as for what you asked engine bolts directly in place no modifications, if you have auto you will need to swap out TC, yes you will nedd to find complete wiring harness unless you decided to go the mechanical DB2 fuel system route. not sure about ac mounting your a/c is on top of engine just like the 6.5 is radiator might work you will need to add a external oil cooler if you don't already have one.

I bought donor truck on e-bay for 2600 swap all part off of it on to this truck it had a vent oil pan where rods where hanging out.
e-mail be glad to help you all i can by the way where are you located
good luck
