Just picked this up this week. 76 250 RV with 340 twin pipes. I don't know the HP. But these motors with the rotary valves were supposed to run pretty good. Power to weight ratio is probally pretty decent.
Those are cool sleds. That one should be worth some $. There is a guy at Vintage Sleds with a 670 in one that he trail rides. Has a cool vid posted. It hauls!!!!
