If you take the pump off, you could measure the eccentric stroke by measuring the distance from the pump mounting surface to the eccentric, turning the engine over to find the low and high points. I am not sure what the correct value would be, but someone here may know.

Any chance the actuating lever of this pump is incorrectly contoured as well?

Turns out the problem was in the fuel pump I rebuilt. I purchased and installed an already rebuilt pump made in the USA. It flow tested at a full pint in less than 15 seconds. Well within the shop manual's required one pint within 30 seconds. 
Thank you everyone for your suggestions.
