What would you guys think about
having the 7580 motor in an 220.

I don't see any reason to do that. A stock engine with some added fuel works good. I like my 220 but will take my 8070 for a day working ground. Quiet and climate controlled.

They are both a 426. I suppose you'd gain the innercooler and whatever gave the 7580 another 50ish drawbar horse. Shouldn't be hard to get a few more ponies out of the 220 without needing and engine swap.

You've already done a 3700 engine (don't know what it was out of) into a 210 tractor, haven't you ?? Pretty much the same swap, except the turbocharger size/orientation is different. I'd use the 220 centered exhaust manifold, turn the 7580 turbo around backwards and make your new connections/lines and maybe a different/altered stack hole in the hood. Everything else is the same I think. The clutch/flywheel/rear back plate, front plate (to allow a hydraulic pump drive) maybe the timing cover, either the water pump or change the lower radiator hose connection location, etc. As with any engine swap to more HP, your radiator won't have enough capacity with a 220 flywheel HP engine (versus 150 flywheel HP) farming on a 90 degree day with the engine at 100% load continually. A day of 75 degrees air temp would be much better. It is certainly doable. Will it make the tractor worth more $$$$ so sell it down the road ?? I personally don't think so. Buyers are more likely to want to purchase an original, nothing altered 220 not a "one-of" version. It's your money.

The 7580 engine develops its horsepower at a higher rpm than a 220 engine, so take that into consideration. The injector pump could be recalibrated to different rpm and horsepower settings if you want. Depending on what you intend to do with the tractor, you could probably just back off the throttle and still have ample power.

Yes Doc I do have an irrigation motor in my 210(MK II 3700)
and it works fine,but as you know I'm not in the field with it.
My thinking in my situation right now is time versus money.
And if i keep the original motor in the barn there is no
chance of losing it on the track.I doubt my daughter will
ever part company with either of these tractors after I'm gone
but you never know and would have the original motor.
