I dought if many have.

It could run into a night mare.


Beside having to get the complete engine with all stuff on it like AC and alt and ps and dist and raditor and all cooler lines and rad hoses and fan and pulleys.
The VCM/PCM computer and all wiring under dash and under hood and even the transmission and 4W computer and wiring and controls and front axel 4W lockin and drive lines setup and speedometer and dask gauge and wiring may have to be changed.

I would stay with the engine it has or trade the Suburban for it for one that already has a vortec in it.

The gain in MPG on fuel might help pay for trade.
And save you a lot of night mares.
Let us know how it goes and,
Good Luck either way you go

Also fuel tank or tanks and fuel pumpor pumps and wiring and fuel lines will need changed.
