You've reminded me there used to be a hill climb in Empire, Michigan (which after a long hiatus is once again gaining traction).
Our friend Fred Meissinger used to run an early Z with a crossram. Fred was a GM executive and was plant manager of the Adrian Manufacturing plant when he retired. Fred passed away about 10 years ago.
Fred Meissinger and car, at Empire, Michigan:
(Me - about to put a super tune on Fred's car; Dad is coming over the fence to prevent me from putting a super tune on Fred's car):
Fred's friend Denny Hall was always right behind him:
Denny was director of GM's Advanced Manufacturing Engineering when he retired. He is still living up by Houghton Lake last I knew.
I took these with one of those old Brownie box cameras.
