I do not see the partial VIN stamp that the US factory stamped into the block in later years (there were two different stampings; one made at he engine plant, and the second at the assembly plant).
The Canadian government was much more progressive and required that all major components (motor, rear end, and tranny) made for cars be stamped with an identifying number three years before the US government similarly reacted to organized auto theft rings required a partial VIN on all parts. I am not as familiar with the Canadian stamping system, but Alan Colvin has the information stashed in his books so I will look and see what he wrote a little later. I do know that all Canadian blocks where cast with the same high nickel content nodular iron as was reserved for only four bolt truck blocks in the US (to prevent the block from cracking in cold Canadian winter weather one would assume). As such they all have the 020 cast into the block under the timing cover to denote the nickel content where US blocks are marked with an 010).
You will need the numbers located on the right front (pass side) engine pad in front of the head stamped into the block. There should be a partial vin number, then your engine info numbers. 3858180 is a 64-67 327 engine casting but thats all it tells you.
There is also a date cast into the bellhousing area on the right rear top. It would read something like B for Febuary, 17 for the day and 5 for the year. B 17 5
You have a 1965 Impala SS V8 with blue interior and mist blue exterior.
Which means it isn't the original engine. It is probably older than a 1965 manufacture date, but that info is cast into the date code on the block and heads.
They started stamping Corvette VIN's on motors going into Corvettes back in 1960; it wasn't until 1962 that they started stamping high performance motors (ones that were rated at more than 300 horsepower). It took a while (and a federal law) to get all motors stamped with a partial VIN, starting in 1965.
I put a picture of that...is there something missing on it?
About this engine stamp, I put a picture of it AND a transcript of the casting that is at the back of the block on the bell housing flange...I'm gonna verify the date code
The car was not a canadian car, she spent most of her life in the USA
You missed my reply above decoding the engine stamp. VIN stamping was not common in 65 except in high value engines.
Looking up your trim tag:
I can't make out the date code, too blurry. Looks like 06C 05C? First two places are the numeric month, last place is a letter for the week of the month (A=first week, B=second week, etc) From my earlier post, your engine was assembled June 10th. Typically the engine assembly date preceeds the body date. So if the body date is 06C that would make sense with the engine date.
STYLE 65-16637 65=YEAR 16637= 2 DOOR SPORT COUPE IMPALA SS WITH V8 ENGINE
BODY BA 13562 BA= Altlanta, Georgia (Doraville) 13562=Sequential number for the body style from this plant.
TRIM 831 831=Blue Interior
PAINT DD DD= Mist Blue (Medium Blue)
The Suffix code HC designates 327ci. with powerglide transmission, full size Chevrolet, 1965, 66, 67, and 1968

You will have to check the casting date for the year the block was made.
You need to check your engine build date with your car assembly date. As David mentioned above.
On your cowl tag right above the " ST 65" is the car assembly date code. We can not read it.
Is it O6C ?? If so then your engine is most likely original.
Remember your engine will not have a partial VIN stamped on it, that was not federaally mandated until the 68 model year. In general only the High HP engines on fullsize cars contained the partial VIN stamping prior to 68.
Confirm the cowl tag build date and post.
Oh, and C60 is Factory Air Conditioning in case you did not know.
Remember, that is the date the block was cast. The stamped date, is the date the engine was assembled.
BTW, I am getting my information from Alan Colvin's book "Chevrolet by the Numbers 65-69". If you find this interesting, you may want to pick up a copy. There is info on other parts like transmissions, heads, distributers, etc. It is fun to check stuff.
"Remember, that is the date the block was cast. The stamped date, is the date the engine was assembled."
^^ Thanks, I did not know that. I'm mostly scouting around the net for decoders and found most info for my car but without a build sheet and without a VIN stamped on the engine pad it gets pretty hard to confirm some things...
