Will a 91 670 engine bolt in to a 99 ski doo summit chassis?

[Snow Guy]

MY current 670 engine blew up, but i found a 670 engine out of a 91 ski doo, it should bole in to my 99 ski doo right?

Will have to use the mount plate from the 99. Use all electronics from the 91.

Motor will sit pretty high being a Rotary valve if it's a S or ZX chassis.

I don't think it will sit any higher than his original blown up 670....lol

Did ski-doo make a 670 in 91? I believe it was a 617 at the time - might want to double check displacement / mounts, etc.

yes first year of the 670 I think was 93 in the mach 1 series....an 95 in the summit.....
