No casting info????

I had the slant 6 replaced in my 65 dart a while back and the good running slant came from a buddy who got it from a buddy. Nobody knows what year of engine /car ect. All I know is it is a 225 slant6 with 1 barrel carb. Here is the stamped numbers on passengerside
7 225 P 5 162E
Casting numbers 0487 & 530-12 on the driversside
