Cummins Engine Identification help please

I just bought this motor for $2000 running. I was told it was a big cam. It’s too late to do anything. I’ve got two small cams now I’m just gonna have to use them.
Here are the pictures of the 1977 NTC 350 small cam
Which includes pictures on top of the injector pump with tag

 

And this next set of pics are the 1976 ntc350 small cam that’s in the truck with spun bearings

 

For what little it’s gonna work if I can make it 400 horse I’d be happy since I blew all my Mad money on this motor. I got a wait to do anything else for a while. I was just trying to get ideas from y’all. I appreciate everybody’s help. I’m going to be requesting a lot more some of these days.

 

Here are the tags on top of the fuel pumps
The shiny tag is in the truck now with the spun bearings it’s a 76 small cam NTC 350,

and the tag with paint on it is on the running motor. It is a 77 small cam NTC 350.
If you can tell me if they are turned up or not and to what I would greatly appreciate it

 

I eventually want a big cam so I can have Jake’s but I have to work with the cards I’m dealt so I’m gonna go through the one that runs put it in the truck and then I’m gonna rebuild the one that’s got the spun bearings and down the road. I’ll maybe trade them both for a real nice big cam.

 

It appears that the turbo is in different positions from the motor that I just got to came out of the Ford and the motor that’s in the International which I don’t know what it came out of but the one that’s on the motor in the truck will not work on the one that’s on the motor I just bought
