51 Plymouth into a 37 dodge

[Old Flathead]

A 1951 Plymouth, 23 inch 218 will drop right in to a 1937 dodge, correct ?

 

Sorry for probably being the 100th person to ask such a question.

Been a few years since I have done any reading on the subject. I had a 1949 truck with a 1938 engine and was interested.

Seems I remember it was around 1935 that they changed the starter location moving it outward and also the flywheel making it larger in diameter.

 

So it seems around 34-36 you had to make sure you had the right pieces to bolt the transmission, flywheel, starter .... 37 you should be fine.

Who is to say that someone did not bolt a 1934 transmission into your 1937? .... IIRC, this is what you need to check to make things work.

There may be some other differences but nothing major to keep it from working.

The first 2 years of the flathead have exposed cylinders without water jackets. So the block is more narrow. This is what causes the mismatch you are thinking of

Old Flathead-

 

Way back in 1968 ,still in High school

 

I bought a rough but 100% complete 37 PLy. bus.cpe. for $25.

 

My brother in law gave me a driver -with no brakes 1951-53 plymouth for free.

 

I put the engine and some parts from the 51+ in the 1937 and made it driveable  on our 1+ acre place in the country. As a non licensed driver I had a ball running it around our yard as fast and hard as I could.

 

So I say to you parts between the 2 cars can somehow be combined to work and make a usable car.

 

Details of the combo are long last to the cosmos!
