Saved From Scrap

This is an old video I took last year as I was parking it for winter. She's still in pieces at the moment.

 

I wish that was my place. Mom and Dad's house. That's why the truck's outside and not in the shop lol. I don't have enough room at my current house to store it while I do the work.

 

Question for you old school Cat guys:

Is there any way to identify which prefix 3406A I have other than the S/N stamp?
The S/N stamp on the RH side of the block by the #6 cylinder is partially erroded away with the years and I can't make out the prefix. I know the dealer was able to pull up the build sheet for it but I don't know if that engine has ever been swapped out. According to the valve cover sticker its the 375 HP version. The head has been swapped out at some point as it appears to be the direct injection head (can't find any glow plugs or related wiring) as well as the head appears to have yellow paint in some spots, rather than the Paccar white that they used at that time. It's definitely an A block based on the fuel pump with the foot long driveshaft attached to it and no cone shaped timing advance in the front cover.

 

I just assumed there was 2 different prefixes because they offered the A model with a pre-cup head as well as direct injected later on. Could you elaborate on that? Mainly just curious because I want to log into SIS and see if Cat has any parts availability for the A's.

 

Mine definitely does not have glow plugs or any of the wiring associated with them that I can find. My injection pump has a tag on it that reads "for prechamber type 3406" and lists an arrangement number. Would that be the arrangement number I'm looking for or is there a different one stamped on the block or valve cover somewhere?
