I have a 98 Foreman 400 4X4 that is knocking badly and will fail soon. I can get my hands on a Foreman 450 but don't know if the 450 will fit in a 400. Has anyone put a 450 into a 400?

 

i havent tried it at all, but when i put my 96 foreman 400 next to my dads 2000 450 i bet they would slip right in.. However, the front drive shafts on the 400 and 450 are different. I dont know if they would work or if you would have ot fabricate one. Other than that im sure its possible. good luck with it, that would be awesome to do.
