Hello Everyone,
I just got a 68 Firebird with a 455 engine block, many numbers on it and I have no idea what most are, I have deciphered some.
Can anyone help me find out where this block came from?
D151 and a 7 and 71 on top which I found out it was build in April 15,1971.
455 is stamped on the engine side.
Other numbers:
C372079 and YC (which means automatic trans) I guess? What are the first numbers?
485428 means 455 HO in late 1971?
A very light tamping 21376313 (not sure since it is VERY light), what are these?
Can anyone help in what the numbers mean?
Best regards
Joey
