pump id help, "912" vs "911" 180 hp pump ?

just got a 97 12v dodge engine cheap- out of a truck with an auto- 180 rated hp. truck had an egr- never seen one around here , we dont smog check-yet. pump is #402 736 912. i was expecting a "911" any difference or timing #,s differnce between the 2 ? is it a good pump ? thanks.

im in the same boat as you. i have a 912 pump from a spun rod engine that i am going to use in my build. wondering if a rack plug is good with that pump? pump came off a ca model.
