Okay. What I meant was, what is YOUR engine's casting #?
 
No, DMV doesn't mess with engine serial numbers. If you truck had a VIN # on the title that was the same as the engine number (this often happened back then, even though your truck has a perfectly good chassis # which SHOULD be on the title), and then if you changed the engine, your truck would still carry the old engine # on the title.
 
If your truck has a CHASSIS # on a plate somewhere, I would make THAT the VIN on the title.
 
As for which engine you have, that's important for ordering parts, as you say, but you don't necessarily have to know the YEAR of the engine, just the type.
 
If you have a 216, then you don't have insert bearings. One tip off is if you drop the pan, you'll see little "dippers" attached to the crankshaft to splash oil on the bearings.
 
It's a very primitive engine and if you are ambitious, it would be nice to put a 235 in there someday.

The previous post to your reply has the casting numbers I found, which are for 1952/53 engines (if my search was correct). I also noticed that above the block casting it say "GM 3". On another forum someone said there should be a cast date somewhere on the right side of the block. I wonder if the GM 3 is the year? As for the vehicle serial number (VIN), the tag in the door frame says "20HPC3181", but the engine says "DR140622CAL". Very frustrating trying to figure exactly what engine I have.

Not clear here. The engine can't have two casting numbers. Which casting number is stamped on your engine?
 
The chassis number is correct. This is a 1950 3100 series built in Van Nuys California in March 1950, and unless changes, the engine would be a 216 of course.

Sorry if I'm confusing things. The casting numbers I found are:
 
head casting #: 3835517 (Research says this is for 1950-53 All 216)
  
block casting #: 1952-53 3835849 (Research says this is for 1952-1953 216 Passenger, Truck)
 
My friend, that was a fleet mechanic for the railroad (long, long ago), says my egine definitely has insert bearings, not babbitt. Maybe I should pull the rod bearing and post a picture.

I think you could buy a bearing insert back then that worked in the babbitt rod, if you modified it somewhat.
 
So okay, you have a 216 with modified bearing inserts and rods. I still think, if you are going to keep and restore this truck, that putting in a 235 would be a good idea.

I would seriously consider a 235, and probably would have gone that route if I'd had know better, but we already invested in a complete rebuild of the 216 head. So for now I'll probably fix up the 216 (have a few other issues to deal with on it) and then look at swapping it out if it ever dies. The truck has been in my wife's family since purchased, so I was trying to keep it stock for senimental reasons. Thanks for all the input.

The 216 is fine as long as you don't try to run it on a freeway. It's perfectly suited to putting around town or on the farm.
