Would like to repower my 7020. What motors will fit without major modifications. Anyone know of someone who has done a repower and what engine they used?

I would probably go the 466 rout on a 7020. Biggest problem with a 7020 was the motor. Same engine as a 4620 which is a very good motor, UNTIL you strap it into a 4 wheel drive and it has the traction to lug the crap out of it all day long. I would think a 466 turbo (4440) or maybe even a 466 turbo and after cooled (4640) would be a great match in one of these.

Just about any 404,466,7.6 or 8.1 engine built in the past 35 years from the 4620 and later can be bolted in there and work. Depending on it's previous application with turbo mounting, bolt holes being tapped etc. Some are tougher other bolt in and run. Tractor application engines should be a easier fit.
