Was there a 4 cylinder motor in 34

'C' is not a part number. The part numbers of the '33-'34 four-cylinder engine had a '46' prefix. There was a Model C in England, but the misnomer for the '33-'34 four-cylinder engine evidently arose because of the letter 'C' cast into the top of all U.S. four-cylinder cylinder heads starting with the '32 models to distinguish the '32 head from the so-called high compression Model A head which had a 'B' cast into the top of it. It is kind of silly given the major physical differences between any Model A head (water pump attachment and water outlet on the Model A version) and the '32-'34 head. There are lots more differences between the '32 and '33-'34 four than just the exhaust manifold and water pump, but with the possible exception of the addition of a four-blade fan aren't important for modeling purposes, as indicated above.

The photos below are of a '33 four. The only difference on the '34 version was a slightly different generator and starter motor.
