What are the main journal and rod journal diameters for this crankshaft, and what would the ID say on it??? (ex. 2y, or A) Thanks for reading this.

 

Can you be more specific as to year, number of cylinders ect. I don't believe I have ever herd of a 136 cu Ford Flathead.

 

60hp model, 17 stud V8, 1937 - 1940

 

Sorry I have only ever heard it called the 60hp Flathead. Try this link I think it has everything you are looking for. I look in my stack of Motors Manuals my dad left me but they don't go back that far
