Came across a 2004 foreman 400 foot shift no display full time 4x4 but engine is locked up. I have a 03 rancher 350fm will the rancher motor swap out on the foreman? And what type of modifications if any would be involved? Seen a lot of discussions of 400 and 450 engines to to the rancher but couldnt find any with the rancher 350 onto the foreman 400. Thanks in advance.
