The flow of air on a stovebolt: horizontal flow into side of air cleaner, 90* turn to go down to oil surface, 90* turn to cross oil, another 90* turn to get back up to carb throat, 90* turn to flow down through carb, 90* turn to enter intake runner, 90* turn to enter port, 90* turn to pass across underside of valve head, and finally a 90* turn to fill cylinder. Now THAT engine is a prime candidate for hot rodding.
