340 engine into a 370 sled?

[PaverMaster]

Bought a z370 for my youngest last year and the motor seized. Looking at buying a used one and dropping it in. Will a Arctic Cat 340 fit in without any mods or will there be a lot of changes? I am comfortable swapping the 370's but I don't want to bite off more than I can chew if changes are needed for the 340

Thanks for any advice and help.

Peace,

PaverMaster

340 - 370

I'm pretty sure it would be a bolt in swap. I think everything is the same except the bore and piston size.
