After you've installed your new oil pump and before you install the distributor, use an old distributor shaft or screw driver shaft(no handle) attached to a drill and spin the pump to see if oil is properly reaching the valve train.After engine installation ,remove the plugs and prime the engine again without firing and check your oil pressure with the dash gauge or instrument gauge if you have one.Replace the plugs and start the engine and let it come to temp and check the pressure and for leaks. If that is ok check for compression,timing,carb adjustment and anything else you that you notice.Also,maybe you can get more info in the MOPAR forum on this site.
