Will a 2004 polaris Sportsman 400 engine motor mount into a 2003 polaris trailboss 330 without any mods? Thanks!

 

Motor mounts are different on both machines as well as the frame,But anything can be fabricated to work along with adding an oil tank,electrical component and harness swap,etc. A lot of work and my opinion not worth it. If you want a larger machine,sell the old one. Dirt Cheap Yamaha, Honda, Arctic Cat & Polaris OEM Parts & Accessories – Cycle Parts Warehouse http://www.cyclepartswarehouse.com/f...2003&fveh=5623

 

If you're just looking for a bigger motor, they used to make a 414 kit for the trail boss. At least it would fit back in with no problems.
