Check the online parts microfische to see if they share the same crankcase and crank. You want to make sure the connecting rods are the same length so that port timing matches up. You may also need the 700 pipe, stator and CDI, and any other engine management electronics. Engines may share the same bottom end, but it will be more than just cylinder bore that makes them different. Look around for good used cylinders, or contact a replater and buy without exchange.
Replacing Jugs
i was told that you can replace the 600 jugs in a rev with 700 ones and they will fit perfect. Im curious if anyone has heard or knows about this and if so do u know anywhere i can pick up a set of new 700 jugs. Thanks

I have read about several people doing this. I think they used the 600 HO bottom end with the 700 jugs and head. Check out cough cough...dootalk.com in the REV section. Several topics in there about it.
Lots of discusion at that other site about this
It's a good option but there is still something better. Send your 600H.O. jugs into Kelsey at RK TEK and get a 734 kit.
To answer your question though yes the 700 jugs will fit no problem. You will also need 700 pistons and rings as well as the head and RAVE's. Cudney has a nice mild trail ported version and was pulling close to 135 ponies out of it. Use the 600 H.O. pipe even with the 734 kit. You are still limited with the crappy series III design limitations with the 700 though. Thats why if you are going through the expense of swapping jugs etc just go the 734 route.

Hey rob7374 i noticed your in manitoba and im in ontario that place your talkin about with the 734 kit where are they located? and would u have any info on how i could contact them? I was stupid and i put a clutch kit in my sled and dinked around with some pipes and when i put my motor back in the sled i forgot to bleed the oil lines and needless to say i ran her so hot she shut down on me and now after all that work i have to get it redone. I made it .6 of a mile YES!! I havent taken it apart yet but a friend that does the pro race sleds for polaris said i will probably have to get the nikaseal redone in the jugs so i might as well spend the extra money and get the bigger jugs for the more power. And since you mentioned that place maybe they can do it all for me instead of me sending different parts to different places and having to wait of it all to come back when i can send it all to one place to get done.
