frame number
Can anyone tell me what year frame pant number STT6448 is for. Was told it was a 64 with disk brake up grade. I bought it for a 64 corvette that I have had in storage for over 30 years. Hope I have not made a very big mistake.

Disk brakes had nothing to do with the frame. A picture of the frame can help. Does the front crossmember have a detent in it

Welcome to the CF! Disc brakes were never available at all for '64. First applications for discs was '65, but you could select the "delete discs" option in order to have drum brakes. Strange, but true.

As you can see I got more than just the frame. Will my 64 body go on this frame without much trouble . Not concerned with staying original, just want to get her back on the road again. Been waiting a long time to do this. Kids out of collage now, my turn. Still trying to figure out what 350 engine that is (Vo213CLR, 3970010) and the year.

It is hard to tell from your pictures but it looks like some welds at the front frame horns and welds at the rear of the frame and it looks like a bolt in cross member? It may be a late model 68-72 modified frame? 65 and up for sure. Need better pictures.

That notch yours has in the front crossmember is specific to '65s and later, so that is not a '64 frame. The notch is for big block pulley clearance.

The big question here is will my 64 convertible body fit on this chassis or have I really screwed up. I bought this from a lady who's husband passed 5 years ago and she is just getting around to dealing with his corvette shop which still has 7 corvettes in it still and have sold about 15. There are supper lot of parts from GM in the box plus used ones on the shelves. She said he was building this chassis for a 64 convertible body. Thanks for any info you can supply.

Half shaft u-joints caps look like big block units. Dennis

Been waiting a long time to do this. Kids out of collage now, my turn. Still trying to figure out what 350 engine that is (Vo213CLR, 3970010) and the year.
Edit: New info from a search online shows "CLR" used in both 1973 for 4 speed trans L82 (250 hp) Vettes, and in 1978 for auto trans L48 (175 hp) for Calif. Vettes & Monte Carlos. Both of these are 350 CID engines.
The casting number "3970010" matches a very common 4" bore block that was built into many 350 CID engines. It was cast from 1968 to the late 70's, and came in both 2 and 4 bolt main bearing styles (have to pull the pan to find out which).
Does the front engine pad have another stamping on it?
Maybe someone else has better or more info.

I'm sure you can make it work if there are issues. They will likely be fixable.

The body mounts on the frame were the same for 64-67 frames, so mounting your body should not be an issue.
Last edited by waynec; 10-06-2018 at 12:56 PM. Reason: corrected "63" to "64" because 63 mounts are slighhtly higher (no mount cushions were used in 63)

Um, maybe I don't understand the Forum members answers, OR, maybe I just don't see the same things in your frame picture, BUT:
I do NOT see the frame gussets at the junction of the rear of the frame at the kickup over the trailing arms. These gussets were added in 1969 to strengthen the rear of the frame which carries the differential.
SO, (I beleive those gussets are the only thing which might impact your 1964 body) I see no reason why any body from 1963 thru 1967 would not fit on this (pic) frame.

I question the "CLR", since Chevy did not start using the 3 digit "C" series engine letter designations until 1970, and the only "CLR" I find is from a 402 manual trans version from a 1971 Chevele or Monte Carlo, and your engine is not a 402 (big block).
Edit: New info from a search online shows "CLR" used in both 1973 for 4 speed trans L82 (250 hp) Vettes, and in 1978 for auto trans L48 (175 hp) for Calif. Vettes & Monte Carlos. Both of these are 350 CID engines.

Short answer, yes it will work. Longer answer is there may be unknown issues as you don't know what may have been modified. In general '63-'82 frames are the same, with slight modifications over the years.
I'm sure you can make it work if there are issues. They will likely be fixable.

The 14S427138 translates to "Chevrolet", 1974 (the 2nd digit indicates year) "4", and the "S" is for St. Louis.
Here is an example (gleaned from the internet):
VIN code format Example: 13N100001
(1 = Chevrolet, 3 = 1973, N = Norwood, 100001 = Production sequence of vehicle VIN)
The trans and engine "match" (from the same Vette).
The 333882 heads could be either 1.94" or 2.02" intake valve heads, and are very common in that time frame.
You need to search the frame for it's VIN number. That will tell you if it is for the same Vette as the engine & trans). I don't have a clue where C3 Vettes have their VIN numbers, but I would look in the same location as the C2 Vettes (which one of the C2 guys on here should be able to help you with).
They should also help you out with the other trans and rear end numbers.

Last picture shows frame number with white paint in the stamping, 69 up gussets at the kick up, bug block half shafts. Front and rear of frame appear exactly like my 64 that I just finished rust proofing the inside of the frame today. On the front, the bumper brackets are installed, which looks odd without the body.

Front and rear of frame appear exactly like my 64 that I just finished rust proofing the inside of the frame today. On the front, the bumper brackets are installed, which looks odd without the body.
This appears to me to be a 65-68 frame and that VIN stamp will confirm the year. I've attached a pic of my VIN stamp on the left kickup at #4 for an example. The 1st digit in the stamp is the year (in my case 6 for 66), then S for St. Louis, then the 6-digit VIN derivative.
I think this frame was used in a roadster because it has the extra body mount horn on each side near the transmission cross member. Couples did not use that #2 mount location.
Like Dennis mentioned, it has BB half shafts, but does not have a rear sway member so it was likely used for a SB car.
To answer the OP's original questions ... its NOT a 64 frame, but in my view it will definitely work for your 64 car. My $0.02. Bill
