I think it's pretty neat too, but not surprising to me. Check out most carb's on 30's, 40's and 50's cars and they're pretty much lawn mower single barrel carbs. It doesn't take 400 hp to be driveable and go down the road at 70 mph. 60-80 hp is more than enough.
As for the carb install itself, I can't help think that turning the whole thing 90 degrees would have solved the dist to air filter problem and made the throttle cable super easy...
