Hello to All, New to the site so I still need to learn the ropes. I recently purchased a 1935 Ford and the previous owner (not the original owner) thought the motor was a 1937. How can I tell if it is a 1935 or a 1937? Any help would be appreciated.

Attached below is a picture of the flathead engine in my '37 Ford. It is original to the car. Now, if you can post a picture of the engine in your '35 which should have its water pumps in the front of each cylinder head....

It is also possible that you have a '37 engine that someone has installed '35 heads on. The the pumps are in the front of the head and there is a provision for water pumps in the front of the block that has been covered with block off plates that is what you have. I have attached a photograph of the block off plate Ford made to enable dealers to install the '37 engine in the earlier cars. Charlie Stephens

Hopefully this works. I have tried to attach a picture of the motor in my car. The water pumps are located in front of the motor at the end of the heads. I never understood when the change was made between dumping the radiator hoses into the top of the head as opposed to placing the water pumps at the end of the head. I need educated.

Yup, looks like you have the "block off plate" Charlie described above....

doghair3, In answer to your question. When the V8 came out in 1932 the pumps were at the front of the head. Beginning in 1937 the pumps were relocated to the front of the engine block and would remain there for the rest of flathead production (1953). This new location has two advantages. First with this design the water is under a slight pressure which raises the boiling point. The design with the pumps in the head sucked water out of the engine slightly reducing the pressure and the boiling point. The second advantage is that the water pumps are now pumping the cooler water from the bottom of the radiator when compared to the hotter water exiting the engine. The cooler water is a better environment for the water pumps. Charlie Stephens

MG Did all the 37 heads have the firing order? I was once told that those were of a French manufacture...

MICHV8 - I've been told that they are British manufacture.... This from a Ford Barn Thread > https://fordbarn.com/forum/showthread.php?t=188996&highlight=1937+Cylinder+heads

Thanks to all of you who tried to answer my question. But I admit I'm a little thick up top. Based an what MG and Charlie said (if I understand them correctly) I can assume My motor is original to a 35 model. Right? I guess I need to get a good book (with pictures haha) My best to all. Tom H.

It looks to me as though your car has a '37 engine with '35 cylinder heads.... It's a very nice car by the way....
