10 lbs of oil pressure on engine break in..........

Chrysler never used an oil pump gasket. Aftermarket kits have one. It is not needed, there are two machined surfaces that mate and seal together. If a gasket was installed it could very well have blown out and caused your problems....
I used a gasket on the last 3 with problems. This could be the exception. I did use a ripped one that i though caused the problem originally but since i put a new pump and unripped gasket im guessing that isnt the problem.

I take it you didn't prime the pump when the motor was out ?
You should get a primer rod 5/16 hex is about a foot long and run the pump with a drill and you can see what the pressure is, HV HP pump should be 70 psi even with a drill.
I didnt get to because i ran into an issue when installing the bushing, it was perfect fit around th intermediate shaft but when i install it i didnt but i didnt realize that until halfway down and then i couldnt get back out so i gambled on that being the problem since it was the only obvious fault i could think of. Now, im thinking how can i get the shaft out while its in the car. I tried everything and to try to pry it out of there.
