We have a 91 chev 1/2T 2wd and a96 Chev Suburban 5.7 4wd - what all is involved to swap the gas for diesel in the Suburban. Is the 4wd a problem? also wiring?
Any help is appreciated
Thanks

Swapping in a mechanical 6.2 - 6.5 is almost as easy as a motor change.
Don't leave even a cup of gas in the tank and lines.
If you have a donor the parts all have a dimple to bolt to, well almost.
Unless you like engine noise move all the acustic insulation.

swap 5.7 for 6.2 diesel

Thank-you for your response - do you think it would be wise to move the engine and trans or bolt to the suburb's
existing trans? Also what about wiring to the dash guages or is adiesel guage cluster needed?

The converter and govenor are different gas to diesel.
You will want both wiring diagrams, there are some things that the powertrain control on the gas will expect to see that the diesel has no output for, to keep it from complaining it needs an input. And the diagrams mostly tell what inputs are needed. The diesel has a couple of outputs that may not be on the dash - water in fuel comes to mind.
