190hp injection pump?

[Smokin59 4x4]

When I bought my 1st gen, the previous owners had roasted the motor, but included with it a short block from a 94, gear case, and P-pump from a 96 motor. This was two years ago, and not knowing a whole lot about the CTD at the time I put it together, per manual instructions, and had a shop time the motor. Now that I've learned alot more, I finally opened the pump up in order to check the plate because of high egt's. There was none. So I got that taken care of and borrowed some tools from a friend to check my timing and perhaps advance it while I was at it. Well I was told the pump was a 215 pump, at the time I didn't know what it meant, but I just found the CPL tag down in the frame that has CPL #1551. and the pump part # is 0402736887. The CPL I found to be from a 190hp motor. But I wonder if the pump is even a mate with the front case so the CPL may be off. Anyone know for sure? Or where I could find out plunger specs to time it?(I have no idea how the shop managed to time it without knowing what it was , maybe the tag hadn't fallen off yet then.) I know it didn't come in a Ram if it is a 190hp pump, so what are some of the applications it could've come from? Does it have the 181 DV's like the 215 pump? or the smaller 180 ones? or different all together. Looking for any help, I've been searching all day, haven't been able to find anything.
