I have a spare engine block serial # U26823 which I assume is a late '29 Block. The engine in my 30-U is serial #1511472. Would the crankshafts and camshafts be interchangeable? With the exception of the timing cover the blocks appear to be the same. The difference in the timing cover appears to be to accommodate a shorter shaft distributer in the earlier block.
The distributor in the 1930 turns reverse to the 1929 is one differance.
