Need help interpreting casting numbers
I need help interpreting these numbers from my 1964 convertible:
VIN stamping: 3120606 F0717RD
Casting date: G63
Casting number: 3782870
Intake manifold casting number: 3844459
GM2
Thanks

Re: Need help interpreting casting numbers (MF64VETTE)
To me the F0717RD is the key. F=Flint engine plant, 0717=assembly date(July 17th), and RD=engine usage code. RD is for a '62 Corvette 327ci/300hp engine used with manual trans.
Are you sure on that casting date, could it be G62 rather than G63. G would be July, 6 is the day of the month. So july 6 casting would match with the July 17 assembly date, but the year does not match up with the RD code.

Re: Need help interpreting casting numbers (Tom73)
It's a 300HP manual tranmission. The block was cast in July '63 and the engine was assembled on July 17, 1963. It was originally installed in a 1963 Corvette, sequence number 20606, which was built in late July. ('63 production ended in mid-August.)
That's a correct inlet manifold casting number for a very late '63 300 HP. "GM2" is the mold number.
You sure your car is a '64? ;) What is the VIN?

As Chuck Gongloff said before, this is an engine from a Chevrolet vehicle of the same period as MF64's Vette, but the VIN serial number indicates that it was not originally a Corvette engine. It has too many digits; there weren't that many Corvettes made in those years.
It seems to me that if MF64 has an early 64, this engine would be a very good match. If the car's build date is within the six months after July 17, it would obtain the most possible judging points for a NOM car. From John Z's earlier posts, I believe that the engine stamp pad is not even judged in that case; i.e. it receives a full 30 point deduction, but the rest of the engine (casting numbers, dates) IS judged.

The preceding "3" is the year, and "120606" is the VIN derivative. A VERY late 63, maybe the last or next to last day. I reckon they don't call you "SWC" fer nuthin'. :D :D

Chuck,
You are right, I just did not dig deep enough to pick up the 62 through 64 use of RD. I will now go and fall on my sword :jester

The rest of you guys - turn in your NCRS cards and walk the plank!!! ;)
Remember, job 1 was sequence number 100001, and the VIN derivative on the pad is this number preceded by the last digit of the model year.

Interesting! You have a fairly early '64 roadster - sequence number 3941 - but the engine is from a late build '63 300 HP/manual trans. Sounds like a complete engine swap was done, but I wonder why.
