Hey! Think one could graft that thing onto a sandrail?

Or if you could fit it in a Geezer Glide does that mean you could haul two *****s around?

Or maybe it's like one of those "autocross" cars, that's supposed to only run for 10 minutes max....

Anyway, pretty silly concept.

Since 350 total horsepower calculates to 175HP per engine I'd say this idea is pushed well beyond the design limit for the HD engine. Even if you could cool it it wouldn't take the abuse very long.
