Long story but figured somebody can help.
The engine is 426 stock build minus cam. Somebody else built the short block (he passed away earlier his yr) I inspected it and it looked good so I finished the rest of the build. Primed it w/drill CCW but no oil pressure via mechanical gauge. Inspected the heads and all rocker shafts and all are oiling. Put engine back together and installed it in the car to break in FT cam but still no oil pressure.
However, when priming the system I can see oil moving by looking into the distributor hole w/drill running. So I pressed w/cam break in (25 mins) because I know it's oiling. Break-in was fine, the engine purred, valvetrain was very quiet but still no oil pressure. Changed oil pump and still no oil pressure even w/mechanical gauge on back of block. Disconnect the copper line and its dry. I took a piece of wire to see if there is any blockage when the sensing unit goes and the wires goes down 4 1/2" and stops....that depth normal? Why is the oil not coming up to the sending unit location? I fired it up today to let it run, no issues, pulled pass side valve cover and it has oil everywhere, another indication of positive oiling. What am I missing?
