The mounts of an aluminum frame 450 are quite different, especially on top. The engine may physically fit in the frame, but I'd say there'd be a bit of fabrication required for the mounting brackets.

I dont think it would be a direct swap, and youd have to use the 450 engine from a 06 or older I believe

how good are you with a welder is the question though, because I can guarntee there would be modifications needed for mounts and such.
