The Stovebolt Site Forums The Shop Area General Truck Talk Casting Number Woes

Hello all,

I wonder about the engine casting number on my 54 6400 truck. The stamp on the pad behind the distributor reads "0021425 F54P". From inliners.org, the "F54P" part is shown to appear on a 3701481, or a 235 c.i. engine made in 1954.

That sounds good--I was fairly confident that I had a 235 anyway, but I'm just curious about my number. I was looking for something on the order of 370XXXX or 383XXXX and didn't find it. Inliners and Hemmings didn't have anything like "0021425" from what I read. Did I look in the wrong place, misread, or is that just a different series of 235 made in 1954?

Thanks,
J.K.

the 370... 383... are casting numbers, not the numbers on the pad, but numbers cast into the side of the block itself [and the head] - the 0021... is the number of that particular complete engine

For the serial number "0021425 F54P", 0021425 is the build sequence number, as red58 suggested; F=Flint (engine plant); 54=model year; P=engine type designation="Loadmaster" 235 used in 6000 series trucks.

Check this thread for the location of the block casting number.

Thank you guys for the replies. I guess I was looking in the wrong place the whole time. I'll check the number in front of the fuel pump and see what it is.

Thanks again,
J.K.
