The Stovebolt Site Forums The Parking Lot Big Bolts 54 GMC 630

Have a friend looking at a 54 GMC 630. It's a diesel powered road tractor. Would this truck have any ID numbers on the frame? Would the engine block correspond with the ID plate on the cab? Thanks Don

Hy don stocker, I don't know for sure, but I don't think there will be frame numbers on that one. There should be an equipment plate on the inside of the glove compartment door, and the serial number plate should have the engine serial number on it, hope that helps.

Thanks 3b. Where is the number on the diesel engine?
Thanks Don

Hy don stocker, the engine serial number should be stamped on the right side of the block near the front above and in front of the blower, hope that helps.

Hi,Don! Does your friend have any pic's??

Soon as it warms up I'll get some pics from him and post them.

You might check for a number on the frame just in front of the right front spring bracket.

If there were or is a serial number that is the most likely place for it.

I do not have an 600 series yet, both my 1953 450's have serial numbers on the right front frame. And those numbers match the S/N's on the door plate and glove box lid.

The S/N does not match the engine numbers, but rather the frame numbers.

Here in California I have found Chevy and GMC trucks were registered by the engine number in some places, and in other places the trucks were registered by the S/N on the frame and door plate. In some cases it was the dealers that registered the truck and in some cases it was the DMV. There was no consistency as to how it was done back then. No VIN numbers were used.

I have changed all the registrations on my trucks to the S/N on the frame and door plates.
