I'v often wondered if we could use snowmobile 2 strokes in light cars like T buckets. a 800-1000 CC engine is approxamently 150-250 HP stock, most are liquid cooled, the engines can be tuned extensivly now because they use EFI, NOS, turbochargers, all common practice.. 400 HP consistant ( w/o spray ) is not out of the ordinary... they have adaptors and stuff to hook them to 4 wheeler transmissions, and some of them can be had in shaft drive. could easilly adapt a smaller shaft to a larger shaft/ yoke., and a lot of 4wheelers now have reverse.
