Flathead L6 engine identification


Recommended Posts

As many others i have some difficulties to find out wich engine i have exactly.
The car is a 1931 Dodge DH but engine may be swaped, because my spark plug threads are 14mm and nor 18mm as the should be. So i have no idea wich spark plugs i need.
So its important for parts i may order somewhere to know about my engine.
Also how much cubic inch it has and built year.
Is it possible to read that from the different numbers on the block?
On the head is 'Silver Dome' -no ext. cooling bypass
