I am redoing my brothers Farmal H. What is the specs for the crank and the cam sizes? He wanted to know if we could put a Super H Kit in it. It has 3 3/8" cast steel pistons with the raised heads on them. I assume they are the fire power pistons, but am not sure. I don't understand your online parts diagram exactly. It looks like I can go up to a 3 7/16" fire power pistons. Is this right. I am trying to figure out if I need to have the crank turned, Thats why I would like the specs. Thanks for your help.
