Oil Pump Fitment
Engine is a 1977 360. I bought the engine rebuilt and did not have an oil pump. I purchased a melling 72s pump.
The mounting neck will not fully seat, which does not allow the pump outlet base to mate up flush with the bearing cap.
There is a "step" (see attached pic)
View attachment 1714966625 in the bushing hole that may be causing the problem. I don't have a mic or caliper that I can get in there to confirm dimensions against the pump.
Has anyone else run into this? What's the fix?
