Keep an i out on Ebay. They are on there occasionally. But like Snowrat said you probably dont have heat exchangers so you will have to come up with a cooling system. You would be better off buying another sled
I forgot to mention That if you do find a 600 motor and plan to make the swap you must get the complete engine wiring harness also because of the dif in electronics between the two along with the cdi for the 600 motor that you pick up.
I have a 2002 600 XCSP. Was thinking about selling the engine so I could buy a 03 800. I can sell the engine, carbs, drive clutch, CDI, cooling hoses from tank to engine, motor mounts, pipe, silencer, basicaly the whole #### longblock for $2500.00, plus shipping (If needed). It has 770 miles on it.
To fit in a 440 fan, you would need to buy the three exchangers for the tunnel, coolant hoses, bottle, etc. Wiring should be straight forward with some modifications. If you can't hook up the premium switch, remember that the CDI always defaults to premium mode.
I'm not real sure on this but i think the 01 fan model came with exchanger built in but they didn't have the fittings for the hoses, but if they dont u could get them at a bone yard real cheap. The upgrade would be well worth it.
