The block that Peter has appears to be a 1946 model from my information that I have. If I read the numbers right ; C59A block is 1946 , stating that the crankshaft is long and high pressure oil pump used. Model C59T is a 1946 , same as above but uses high torque cam and heavy duty exhaust valves. These configurations are what came from the factory originally, but you can build most of these flatheads up from many assorted parts, and most are interchangable. The crankshaft used in the C59A and C59T blocks is a 99A-6303 , using high pressure oil pump ( 65-70 lbs ) There are about 6 types of crankshafts used in the common types of flatheads, but I thought they were all bascially the same length.
