Need help to identify my engine

[gsx_martin]

Need help to identify my engine.
It is a 6-inline and is installed in a 1952 GMC 253-22, but I'm pretty sure it is not the original engine.
I found a number located directly beside the engine oil dip stick. Number is: B228370750 maybe the last digit is a C instead of the 0.

Thanks
Martin

post a picture of each side and the valve cover

The number comes out to a 1952 228 cubic inch GMC motor

Thanks.
I had read that there is a 216 installed in the 1952 GMC 253-22. But it seems to be wrong.

Nevertheless I will takesome photos of the engine and will post them tomorrow

216 is chevy motor. GMC had its own truck motor until the early 60's
if it is a 216 then its not original

47-5? GMC got 228, 248 or 270 cubic inch engines, never got a 216.

dwcsr is right, the first three numbers tell you the engine displacement of a GMC motor, the leading letter is the main bearing clearance corresponding to a list.

your engine number to me indicates its the original engine, replacement GMC 228 are usually zero'd or X'd out or just plain blank past the displacement.

From what I could find 52 was the last 228, 248 was 53 up and 270 larger trucks

228 was available after 52, 53 and even some 54, 248 was available (and standard) in 3/4 ton trucks from 39-55, 270 was optional for everything but 1/2 ton, 3/4 ton and up.

I just took apart a 49 GMC with a 248

Hello!
Here are the photos I have taken today.
I guess it is the right, maybe original, engine.
The manual, where I had read the normal engine size for 1952 GMC pick up is 216cui is definately wrong

Definitely a 1952 GMC 228

The problem with identifying GMC is that they didn't go strictly by year like Chevy did. They used serial numbers not VIN numbers that would fall in a particular year.

B228370750 was 1952 but B228370749 could have been 1951 and register both as 1952's or 1951's depending on what state or country it was registered in.
