[oletrucks] Engine identification

[Spinningroach@aol.com]

Hi guys (and gals)

Does anyone know what the numbers 10 and 11 that appear on a '68 327 engine 
pistons mean ? Is it possible to tell from these numbers that the engine has 
been rebored, and if so to what extend or on the opposite that it's fully 
original? (The upper rings have a 0 on them - nothing on the others)

Thanks in advance for any input! JP
