Need help decoding engine numbers please
Hi, I just purchased a 327 engine and the owner didn't know what it was from but I believe it may be from a 66 'vette. Here are the stamping numbers:
Rear engine block (near bellhousing): 3858174
Pad in front of passenger head: FO7II2AS
Heads, under valve cover: 3890462 & F276 & GM15
I would GREATLY appreciate anything you can contribute to helping me decode this engine. I have my fingers crossed that it's something I can use for my first rebuild. Thanks in advance! Malo

I am not real good with this numbers stuff but this what it looks like to me.
3858174....327...64-67
3890462....66-67...302/327/350..Camel hump,no accessory holes,64cc chamber
F276 I think is June 27 1966

07 = July
1I = the 11th day
2AS = ???? As John stated there should only be 2 characters not 3.

FYI, it would not be a Corvette engine with an AS- according to Noland, all 66 327's started with a H or a K, not an A. Most had 461 heads, but 462's showed up late in the production year.
The extra digit makes it a plant stamping error or a restamp error maybe? If the engiine looks like it is original, not decked or bored, it may have been a GM production error.

The only 60's Flint engines I've seen with odd 3-digit suffixes were marine engines (Mercury Marine, Crusader, etc.); that's probably where that one began its life. With a very few rare exceptions, there were no 3-digit suffixes until 1970.

The "SB" suffix was used on '62-'64 327/300hp in full-size cars; the VIN derivative stamping on that one says it's from a '62. What's the block casting number (U.S. driver's side rear flange) and the casting date (about 5" toward the U.S. passenger side from the distributor)?

I recently helped a friend sell a 64 Impala with a 327 / 250 hp engine, full option car (S suffix code). The pad did not have a VIN derivative.
Perhaps this varied from assembly plant to assembly plant as the VIN derivatives were phased in throughout the 60s.

Pretty unusual to find a 62-64 low hp (250 / 300 hp) engine in a passenger car with a VIN derivative on it.
