TDL could be

1972 307 2BBL automatic

1980 350 4 BBL automatic

Not with an 010 block. That's a 4" bore casting. The 307 is smaller bore & wouldn't use that block. I almost said the same thing....Joe

Perhaps not true, but I asked answers.com and got this. True?

Stamped Code: V0202TDL

V: Indicates the engine was produced in the Flint, Michigan plant.
02: Refers to the day of the month the engine was built (February 2).
TDL: This is the engine suffix code, which indicates specific details about the engine configuration:
T: Typically denotes a truck engine.
D: Indicates it is a 350 cubic inch engine.
L: Suggests it was used in specific applications, often related to heavy-duty uses or particular vehicle models.
Cast Number: 3970010

This casting number is associated with the Chevrolet 350 engine block, produced from 1969 through the early 1980s. It is a common casting used for various small-block applications.

False. Joe's answer is correct.
