engine swap

I've got a 03 rancher 350 and I have a foreman 400 engine that needs a rebuild.

Im trying to figure out what are the differences between the foreman and rancher? Mostly drivetrain differences.

Will the 400 engine drop into the 350? I would have to bore out the 400 cause it got sunk a while ago and I would like to swap it into the rancher but not sure how difficult this may be.

I'd leave things as is. The 350 will run circles around the 400 stock. Its by far a lighter machine. Just look at the the difference in engine size. 350 is way smaller. If you tried to swap you'll get into clearance issues and driveline problems.
i seen a foreman 450 motor in one and its sweet
