"What do you think is the highest streetable and naturally aspirated horsepower per cubic inch that is possible from a Flathead Ford? What about the same question for race engines?"

This will generate some arguements, I'm sure, but for "streetable (very subjective), my educated guess, having seen 3 well built flatheads on a dyno, is that about 0.65 HP/CI average. Then there is the race flathead that Ken Kloth built, raced and set records with. It is about, not quite, 1.1 Hp/CI. Not really streetable, but was once or twice driven to the local cruise nites. Helpful?
