New engine issues

O I almost forgot someone one here was asking me about metering jets and springs. As far as I know they are stock one that came in the edelbrock 600 ? I rotated the engine with no plugs and only the starter hooked up till my after market oil gauge pumped up to 70 psi cold . I will tear carb apart and inspect the numbers on jets and rods etc. The engine after fully warmed up has 50-53 psi oil pressure. Every thing on the engine is new from the performance harmonic balancer down to the spark plugs. So it's got to be a carb or timing=distributor issue?
