Default Small block Chevy engine suffix ?

Can anyone come up with any possibilities on what this might be?

V1024OLA not real sure about the O, but that's what the dealer read to me off the block. Appears to be a 283 or 327, but who knows. I don't have any of the other numbers except a VIN.

135S4063876 stamped on pad. Also read by dealer and not for certain.

Thanks

Could the "LA" be "IA"...?

That's one consideration, another is CLA, but that's a 427.
This engine is in a 61 Corvette with a powerglide. Looks more like a 283 in pictures. I guess I'm going to have to look for myself. It's several hours away and I was hoping the code would strike something in someone's memory bank.

........maybe. If it is in fact V1024OIA, the "O" would indicate Oldsmobile Motor Division and it would be from a full sized Olds.

OTOH, not knowing if the dealer read it correctly or even completely, if the last 3 characters (from the post 1969 3 character era) are CLA it would a 1974 or 77 L48 Corvette engine 350 4bbl with a turbo hydromatic.

I think you need to have the dealer send you a picture!

Good point - no Corvette model year ever had a run up to 63,876 units!

Sounds like the Olds might be the best guess.

We know this much just from the numbers

V1024OLA

V = Flint engine plant (1967 and later)

135S4063876

1 = Chevrolet car (not truck)
3/5 = year 1973 or 1975
S = St. Louis assembly plant
4 = Check digit
63876 = sequential VIN for that vehicle type (over 68 thousand vehicles)

The VIN derivative has too many characters

Let me propose the following:

The first 3 characters are either:

13S or 15S ... I am guessing that the 5 and the S are really the same character, so 13S is my best guess.

The 4 is a check digit. Te check digit of 4 was used on Corvettes from 1973 to 1980. It was most likely used on other vehicle types as well.

Now the 063876 is the challenging part. It has one too many digits. The question is ... which digit is the extra digit.

Lets go back to the engine code of V1024OLA. This engine was assembled on 10/24 (October 24th), so we can take a guess that the car it went into was assembled in late October or early November.

Lets look at the possibilities...

1. 06387
2. 06376

'There are others, but these two make the most sense to me.

So, if we really have 13S406387 (or 13S406376) that "could" mean an early November built 1973 Corvette. 406054 was the last 73 Corvette built in October of 1972. Roughly 300 cars later would be very early November, 1972.

Now put it all together, with a lot of "ifs", and you get

V1024CLA (the O is really a C)

13S406387 6387 car built

and this becomes a 1973 Corvette base motor, auto trans.

Yes, this is a lot of guessing...

Thank you for all the computing. I've almost talked myself out of this car because of the combination of unknown engine and powerglide transmission. I can get another with "matching numbers", 4 speed for the same dollars.

That makes the decison almost a no-brainer.

But check the bodies carefully. The mechanical stuff is easy. Get the one with the best body (not paint, body). Fixing improper body repair is expensive.
