According to a chart I found on the net your first four numbers mean

D = Year of 70-79
4 = Year of that decade meaning is it a 1974
A = Means a Ford
E = Is the type of part ie: Engine

So the answer is your have a 1974 Ford Engine

There rest of the numbers and letters are a bit more confusing when reading the charts explanation but they really aren't as important as those first four. I don't know which site I found the chart on but its listed as a "Ford engine/parts explanation" chart. You might want to seach under those words.

Hope this helps, good luck
