Glad you are getting better Jerry. My Dad flew in them B-17's but he passed a long time ago. I hope for the very best for your Dad. I was talking to one of the "Old Guys" in the car club. They had a "hill climb" it was a stop watch type affair. Sounded like fun. The rules were simple. Inline or Flathead motors only. Can you get 160 HP from a Flathead V8? Maybe. Can you get 160 HP from an inline 6? Maybe. Keeps things close. And reminds us, there were limits to what the hot Rod guys could do back in the day. And why Wayne built a 12 port head. No one goes to that much trouble if there is an easy way.
