A Flathead in Engine Masters?

I'm sure there are/were flathead engines capable of more than 1Hp/CI. I think Pete in Washington State has built a few.
The only engine I am personally familiar with was the Ken Kloth XFPro record holding Ford flathead.
It displaced 267 cubic inches and dynoed at 280 HP @ around 5700 rpm. It had 109% volumetric efficiency. The engine was always shifted at 6200 rpm. It was naturally aspirated.
Again, I'm sure there were/are more.
His record still stands after 26 years
