Use a Polaris rear suspension, then you can use any motor with chain drive. I am in the parts gathering process for a simular project. I am going to use a sno-mobile engine and a jack shaft to get the belt drive to chain, also will give me more gearing options off of the jack shaft simply by changing tooth count on the front and rear sprockets. Just an idea, good luck on the project.

None of us are capable of screwing things up as bad as a group of us.
