Now, that could make sense or maybe there were some Racer types loose in the foundry who had found some really good core boxes and made sure that special projects used these pieces.

Has anyone ever seen a '61 or '62 date code 461 casting that was NOT a 461X? I haven't and I have seen 20 or 30 of them in junk yards.

Dwight, according to the source below and other sources the 461 and 461X casting numbers date back to 1961 (first 327 engines).
