Default Anyone ever put a snowmobile twin motor into a quad?

I have a 94 polaris trailboss (2wd) that i messed up the crankshaft on. Anyways in pursuit of a new motor, i found that it is way easier to find sled motors than ATV motors.

obviously there are hurtles to overcome here like the fact that the second cylinder would stick out the right side of the quad, and exhaust would be interesting, but is it do-able?

If successful, it would sure be one MF'er of a ATV....

I know a couple people at work that put 700 twin Polaris engines on motorcycle frames and run in the 9's in the 1/4 mile.

anything can be done!! The older trailblazers aren't that hard to come by, I would think you could find one with good motor pretty cheap!! it might not be cheaper to put a snowmobile motor in after you finish paying for all b.s. you will need to make it work!!

do I have a deal for you!
I have been saving an engine for a project and its been on the bench in my barn for years & years. its one of the first 340 Rotax twin free air engines that came in the `75-76 TNT f/a chassies. its a complete engine minus the oil resivoir and exhaust. the ignition is shot thats why I got it, thinking I could find another. in its day it was around 60-70 hp. I have the original twin 38mm Mikunis to go with also
if you can get some help from a good skidoo guy you can probablly set it up easy.

I would think $100.00 for the engine is a good price to get it out of my hair.

thanks for the input guys.

I have a buddy that sourced me a 440 twin polaris engine. Complete and a super good deal.... probably gonna go with that. looks like the only hurtles are getting it mounted and exhaust, other than that, just plug'n play...

If i get it goin i'll take some pictures.

BTW, whats the name of the salvage place...i would love to check that out.
