Hey guys Ive got a 1995 583 Formula Z that i just rebuilt last year... new pistons, crank bearings the works and now she can go.... but for next season i want to get a lighter sled with around the same power or more.... i was thinking of swapping my new engine into a smaller chassis so I dont have to spend alot of money on a new sled and i dont have to let my new engine go to waste. My plan is a summer project to put my new 583 engine into a 1997 mxz 440 chassis. She could be a nice little sleeper and lighter too. My only question is do you guys think the engine would fit? Also if it does what carbs and airbox should i use? Thanks

Should fit.... I cannot say for sure so measure the mounts. You would have to at least use the 583 Carbs, but I bet you can get away with the 440 airbox if the 583 does not fit.

arent they the same chassis???

no the formula has the old heavy whale style chassis and the mxz has a newer lighter chassis.... i love the 583 engine and it has always been good to me and had power... i just want to find a lighter chassis to throw it into to possibly get a little more fun on my sled and for ripping around... im either doing that or if i find a good deal on a 1997-2002 600 or 700 range sled... preferably ski-doo
