You can switch them. You need to change a bunch of parts. Oil pan, timing cover, turbo neck, flywheel, water pump, valve cover, fuel filter and mounting, injector return lines, thermostat housing neck, throttle linage, those are the ones off the top of my head. Have the 6620 injection pump governor changed, it is set to run a constant speed.

The rear frame rail bolts hole are larger on the JD 6620 motor. They are in the correct place just you can not use the original tapered shoulder bolts. I just sue grade eight regular bolts and never had any issues.

It makes for a good swap if you have the injection pump set up correctly. If not they do not work the best.
