Ted:Based on info I see, this could be either a 69-72 396/402 V8 Big Block or a 69-73 454 V8 big block. Used on Camaro, Chevelle and Chevy II's. The CE060689 is a Chevy Replacement number and I believe is was from theTonwanda plant. C=Chevy E= Engine, 60689= the sequence number of the engine. Not sure what T031867 is, the "67" does not match any codes I have seen. The T should stand for the Tonwanda plant 0= 1970 3= March and 18- 18th day. The 67 no idea.
