engine Id any suggestions

[oldmopar]

I recently picked up a 48 1 ton (b1d) dump truck and it does not appear to be the original engine and trying to figure it what it is out of any suggestions would be appreciated. I can not read the engine # I hit it with a wire wheel even tried some chalk but the numbers are impossible to read either never were or worn or ground off. I Was looking for a casting date but only found 2 sets of number

63

GWC3

L193

I did a compression test ran from 160-140 and it has the newer style connection by the water pump so that has me thinking that its newer engine then 48. But the casting date or what ever these numbers do not make any sense to me. It is a 23" head.

here are a few photos of the engine and one of the truck .

I would guess since it's a 23 inch block, it's a 230 engine. In some very old threads on the old forum we discussed how some engines did not have a serial number, if they were rebuilt by a local shop. Guess they ground them off at that time from what I remember about the discussion.

Somewhere, either in front of the distributor, or behind it there should be a clock in raised symbols on the block. Should be some numbers there that have a date. That would at least tell you what year the engine was.

That is what I was looking for the number I found were where I have found casting #'s on other engines but those number I found did not help so I threw it out here.

Chrysler sold bare blocks (and unnumbered) to commercial rebuilders, like Jasper and others. They would build the blocks up ans sell them through their shops and installers.

They were supposed to put their number on them as they were built, or they were supposed to rivet a rebuilders tag on the side of the engine. Look between the generator, and the oil filler tube and or the oilfiller tube and the distributor for a metal tag or the remains of a rivet.

Interesting information the 3rd photo from the top it has what looks like it could be the tag with rivets you are describing. I have this truck outside between some sheds right now when I get it inside I can give the engine a better look over but that still is a good possibility as the truck looks like someone restored it a while back. It has what I think is a pa inspection tag from 2004
