HMMWV engine into H1 Hummer, Need Help

Run across a Military rebuilt 6.2 engine (drop-in) and want to swap it into my blown 1992 H1.

I know the HMMWV engines are set to run off 24 volts so what kind of changes/upgrades will I need to make to get the HMMWV engine to run in my H1?

I am going to do the swap myself...never done one before but feel I can tackle it.

My H1 is the limited edition and #50 off the production line. I want to keep it as stock/OEM as possible hence the reason for the 6.2 vs. 6.5/6.5TD.

Any help would be greatly appreciated!!!

should be able to swap the glow plugs, sensors, and the top cover of the IP and you should be good. also want to swap over all your original front eng accessories.

Many Thanks.....This may be a dumb question but what do you mean by "IP"?

i hope you dont live in an emissions testing area
