Nice engine you got there, I have built the engine myself and just dismantled it as a friend of mine from USA sent me some close up photos of the original engine at the Ford museum and I found out that the original engine had the conrod made from 1/2 square bar and not from a pipe and the crank did not have a counterweight, it did not have notches cut in the cylinder for the conrod to pass. I am trying to make the engine as faithful as possible so I have started making the necessary alterations!!
