Cummins Engine Identification help please

Hello everyone I’m back, so I got a good deal on a Cummins engine and I went and picked it up last weekend. The data plate is missing. I wanna verify what this guy told me about this motor. I’ve been on Google all day there’s gotta be an easier way to punch in an eight digit serial number. They’re just has to be a way for it to tell you what it is without jump through all these hoops. That’s why I’m on here asking you if you can give me any help with his eight digit Cummins Serial number I would greatly appreciate it. 10633996 thanks

 

So is this a small cam engine or a big cam engine and how do I go about getting my dataplate and all the information I need and want for this engine?

 

I don’t have a good picture of the cam follower boxes, but I will when I get off work at 9 AM. Here’s my problem I was told this is a 1977 big cam 400. I didn’t want to mention that until I got some information from somebody on here. I’m building a cab over show truck and I want to restore this motor. I need all the information that I can get on it.

 

So now I’m hoping that you’re wrong on the CPL 160 part lol

 

I don’t know if this helps but I have a 1976 small cam ntc-350 in it now with spun bearings
These two motors look nothing alike
