Help with engine identification.
I have two sets of numbers near the timing cover.: 1. 29A121440 .....but a 11 was stamped over the 40 at the end so it could be 29A121440 or 29A121411; and 2. 0448245. I believe the last 7 digit number is the engine block code but I can't find the is number on any of the Pontiac identification legends. The 0448245 number has a YS below it.

There is no displacement stamp on the engine. Beside the distributor A229 is stamped which I believe means the block was manufactured January 2, 1969.

How could I find the displacement?

The YS was a 1969 Pontiac 400 4bbl. with Automatic, 350HP 455 Torque, most likely from a GTO?
