Was there a 4 cylinder motor in 34
 

I thought I read that there were 4s in 34 and thinking about building a model of one,would they look similar to a A motor with the exception of a fuel pump. I can get plenty of A motors in 1/25 scale.

Yes there was.
Model C. More like a B engine than an A,
but like an A enough for a model!
I think!

add the fuel pump and eliminate the right side oil tube and your model will be close enough

Also 3 bolt water pump.

C is a part number not an engine and does not mean it has a counter balanced crank shaft. It was and is a B engine. The only real difference between the 32 4 and the 34 4 was the exhaust manifold and water pump.

Tony, take a look at post #5 to get the straight skinny on the mythical Model 'C' engine!

'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.

If I may add the confusion to the misnomer was complicated by ford coming out with a counter balanced crankshaft. Coupled with the C on the head what else could it mean? In the end nothing. Those are nice pics with some rare parts.

Thanks for the pictures,the motor looks very similar to a A motor and my concerns were if it had a down draft carb,different distributor,different water pump and lower radiator hose locations so I think I could use a motor from a A and just have to duplicate the air cleaner and will be close enough.

Ford's part numbering and identification system was always evolving. The single alpha letter was to designate a change to that part. Ford later changed the design change indicator as a suffix at the end of a complete part number. The heads for the V8 sometimes had the single digit alpha letter, for example the ones in 1940 or so that just had a big A on them. Then on the post war engines they evolved to 59AB which gave both the engine designator and the design change.

Actually you can skip the air cleaner as that was originally special equipment, optional at extra cost.

David
Isn't that air cleaner the "Heavy Duty" cleaner used on V8"s as well?

It looks like an A motor but is not. The oil pan is different as is the transmission mating area. Half the bell housing is part of the B pan. I also believe the torque tube length is different for V8 and four cylinder engines.

TRUE.......'33 and '34 torque tubes and drive shafts for the 4-cylinder engines are 1-1/2" shorter than their V8 equivalents. In other words, the '33-'34 4-cylinder engine was 1-1/2" LONGER than a V8 engine. This was NOT true for '32 D-shafts and T-tubes. DD

I took this photo back in 1975 and it shows a 4 cylinder Australian 1934 Ford Roadster. It was one of two 4 cylinder 1934 Ford Roadsters at this event. I have not seen this car since.

This is the second 4 cylinder 1934 Ford Roadster that attended the Run back in 1975, as mentioned in the above Post. The top photo shows the owner driving at this event in 1975 while the bottom photo was taken in 1978. The car still exists, but is now a Street Rod and the 4 cylinder engine has been replaced by a Flathead V8.

There are two Auz 4s here trying to get pics

David, was the 32 exhaust swept back design a one year thing. The 4 in your pic seems to have a exh manifold going straight down.

I am not going to get very picky,I will use a V8 trans since the A trans could be different and add a fuel pump and try to duplicate that air cleaner and that will be about it.
