Inliners International Forums General Discussion Engines Engine Serial Numbers

Hello all
I have tried a couple of searches and have come up with unrelated topics so I guess I have to ask if anyone can identify an engine for me.

It's what I suspect is a late 1960's 250 Chevy as I have bought a fuel pump, points, cap and rotor for it guessing at what it is.

There is a number stamped behind the distributor that reads
F1IIOSKT.

I bought a 1955 GMC pickup with this engine transplanted into it.

Any help would be greatly appreciated!

Thanks---DAC

Hi GMCDAC . . .

I think that you will need to check the pad behind the dizzy again . . .

The code makes sense to a point: 'F' Flint '11' November '10' tenth day of the month - but 'SKT' doesn't appear to be a valid application code:

Thank-you stock49, I will recheck it and correct my information!

Oh also thank you for that link!

I did check it again and took a couple of crude pics that I don't know how to load here but the OSKT is quite visible in them.

the first part of the number looks like this sounds- F-one-eye-eye. Then after that is the OSKT.

Maybe someone stamped some bogus numbers on it after a rebuild at one time or another. Thanks for trying.

Hi GMCDAC . . .

Well then I am scratching my head. First and foremost, if it is a sixties vintage engine then there should only be 7 characters on the pad:

If there are eight then it is post '70:


But given the letters in the suffix it seems unlikely that is a newer engine.

So we have what looks like 'F 1II OSKT' . . .

If the first character after F is 1 then we are looking at late in the year. Is the second number a one or and eye? One most likely. What if the guy wielding the die on that cold November day canted the die to the left and imprinted the square edge of the die itself as well as the left edge of the '1' on the face of the die?

That would account for the extra I . . . eliminate that and we're back to seven characters.

So now we have F 11 05 KT. (Cause 'S' in position 5 doesn't match the known codes):

and neither does a K. Sure it isn't an H?

F1105HT would suggest a 62-64 194.

How about the block casting # found near the dipstick. You can also get the date code located very near this area too.

Hello folks,
The number I gave is what is stamped on the block. I cleaned it up better and it is sharp and deliberate. The block number is
3850817 which is a '62-'78 230 or 250 as checked in this sites casting# page.Maybe it is '68ish or newer with the spin on oil filter? It has a point distributor but that could have been changed out at some point.

Thanks again---DAC

Hi GMCDAC . . .

Sometimes I get single minded - I was only looking at passenger car application codes:
YearOne


Looks like you have a block that was originally in a truck:
67-72ChevyTrucks.com

So the engine came out of Flint 'F' in November '11' on the tenth day '10' with an application code of SKT. The circa '75 manual pages posted on the Chevy Truck site indicate a '66 G10 with a 230 and manual transmission.

Note sure what the additional T designates. Could be some kind of 'fleet' build. Some car codes use T to designate a Taxi.

Stock49,
I sure appreciate your persistance in this matter! I have been having some "firewall" problems posting.

That explaination makes good sense if an error by the code stamper is taken into condsideration, which is certainly not out of the question.

I sure thought it was a few years newer than that and hoped for a 250, but that's OK.

Thanks---DAC
