Guy is trying to sell me a small block 327? Please help identify.

Every small block was in a corvette right! lololol Just wanted to get that out of the way. So these are the numbers that the motor has from the crappy pictures he is sending me.

Casting Numbers 3858174

Front Pad Stamp: (I think FOI22YWC)

It is coming back a 327 2 bolt main but I am just curious what it was in.

Thanks
Jay

 

I show it as a '66 Vette block. Couldn't find your front pad stamp.

 

when we were kids in the 60s, we'd look up the 2 letter suffix in OUR Motors manual.

Nobody has manuals anymore, it seems. Those books gave the make and model with the engine code, too

and then the world went all modern and chevy went with 3 letters at the end of the decade, and our books were too old

expect a comment here

 

online, not sure if there is more

 

1964-1967 car & truck, '66 Corvette used the 3858174, according to the book "Chevy Casting Numbers 1955-1993".

 

Do you have the date code? This is located at the rear of the block on the side opposite of the casting number. This will narrow the year down. Sometimes the same suffix on the engine stamping was used for different engines, depending on the year built as shown by F&J's post.

 

I remember those! i wish it was that easy. I found the casting numbers easy enough but the stamped number in the front that is another story...

<table border="0" width="100%"><tbody><tr><td>1964-67 </td><td>3858174 </td><td>327 </td><td> - </td><td>- </td><td> 2</td><td> car, truck</td></tr></tbody></table>

 

That is what the guy is toting it as. I told him to get the numbers off the pad. The only ones I saw were FOI22YWC
Jay

 

That is exactly what I found man.
Jay

 

I found the casting number 3858174 referenced in the Corvette Black Book, as for a '66 Vette.

 

might be corvette truck, 1/4 ton

That prefix looks way wrong to me. the first letters are the engine plant, and a common one is TO for a new york plant


anyways, those old books would tell plant prefixes maybe?, especially my 67 and 69 edition, but it's too cold to go to the shop right now. I will go later tonight to fill the woodboiler; if nobody has a book by then, i will look.

 

I am going to get him to get me the numbers again off the front pad. Like I said crappy pic. I appreciate you looking that up man!
Thanks
Jay

 

Can you post the crappy pic of the stamped number?

 

I can only think of 2 prefixes right now...from the 60s stuff we had. One was F or FO? for Flint plant, and TO for Tonowanda NY plant.

Maybe someone knows any more prefixes for 1960s sbc

did vette have it's own prefix? I sure don't recall that

 

F and V and T are the prefixes for the 3 Chevy engine plants. The 0 is part of the date, the first nine months have a leading zero (after they started making them all 4 digit date codes in the late 50s)

YWC is a 3 letters, 1970 and newer, but the block casting number is for a 327 from the 60s, so my guess is the stamping is hard to read and was not read properly. Should be a letter, then 4 numbers, then two letters.

 

Here is the pic!

 

F0122YWC

interesting...from a similar thread a few years ago,


YW is the suffix for a 1966 C60 (big) truck 327 engine.

They also used CE or R to designate "parts counter" replacement engines, perhaps it's a replacement engine?

 

And casting number!
Jay

 

Shit my eyes must be bad! lololol that O is a C! Good eyes man!
Jay

 

I just decoded mine a few weeks ago. This might help.

Ok so what do you guys think the block worth? I currrently have a 1965 327 in the 55 but I was thinking of getting another block just in case.

 

For the C2 series, the SBC stamp pad should all start with F from the Flint location. all C2 SBC's came from Flint.
F01 = Flint, jan 22

 

100 bucks is all I'd pay for a bare block.

 

With crank and pistons? Short block? Has stock bore too.
Jay

 

I'd be hard pressed to pay more than 200 with those parts, 250 if I really want it. A complete core with heads and intake can be had for 250-400. I have the same, 1965 Virgin short block Core, and I paid 200 for it. I have been offered 250 a couple times, but turned it down. All depends on how much you like em, and how hard you want to run it. When you need one, They can't be found.

 

I hear ya man!
Jay

 

It is FOI22YWC on the front pad he got back to me. Any ideas? Is this a replacement block?

 

Gasserkid...in 1966 and 1967 Chevy engines there was sometimes a suffix to the assembly code that had to do with what carburetor was on the motor...I have seen ones that end in an H (Holley carb) so perhaps ending in a C means it had a Carter carb?

Normally a regular code like yours isnt a counter exchange engine...a CE prefix does or sometimes a C..

 

a common 327 number.....
