Flat Head Six Engine Numbers That Start With "D"
 
 
Dodge used the letter D as the first letter in Dodge Car engines, so an engine that has the first letter as a D is most likely out of some model of Dodge Car.
 
The list below is all the Engineering codes for each model of Dodge Car that could be found at the time this list was made. The Engineering code is normally the code that is used as the beginning of the engine number on these vehicles. Most of these codes will be followed by a sequential number that would help calculate when the engine was made if a list of starting numbers was available. These codes are in order by first letter, and then numeric order, not by year, or type of vehicle.
