George:
Something else to be cognizant of is that the engine in your truck may not be the original engine. It may still be a 216, but it may be from a later (or earlier) year. If that is the case, the letters DBA won't be applicable.
(For instance, mine has an engine in it that starts with GAA.)
If you could post the vin on your title, those of us with the Art Decos can tell you if it's a body serial or an engine serial easily enough.
