What he said ^^^.  Also check the crank runout, there is a limit to how much runout any oil pump can survive, and Harley has a BS maximum tolerance that is well above that limit.

Thanks for all a helpful information.

PDI-Racing does offer the TC3 pump and camplate at a good price!

Once I crack her open, I'm sure I will have some followup questions.

Thanks again
Jim

Just curious.
Other than enough pressure to work the hydraulic lifters, (whatever that is?) why do you need more oil pressure. More flow, yes maybe, which would increase the pressure, but just increasing pressure? Or is the pressure gained by increasing flow.

Pressure is needed for lifters and chain tensioners.  Otherwise, good scavenging and constant flow is important.  Excessive pressure only creates heat.

When checking run out, what are the accepted tolerances? Suggestions for outside of accepted.

Thanks!

oil pump problems will start around .006,that said,acceptible max crank run out is .0035 (here anyway) anything above that,we recommend have the crank done

There was a group of pumps that were sent out without the dowel pins, item #7 in instructions, that connect the sections. Installers that were not on their game can miss this. The sections then are not in alignment.
