When I was the Facility manager at a kids camp I put a 340 snow mobile engine on a tri sport. I took one ride....brought back to the shop and dismantled it. It was WILD!Buddy had a go cart built using a snowmobile as a donor. Eskimo with a single cyl sachs 340. 80 mph and got there quick. Imagine steering so bad, that it would take both lanes of a two lane highway. Raced a firebird 350 4 speed. Go cart had the lead to about 60 mph.
