I just finished rebuilding my 440. I tried to prime the oil system before I installed the valve covers. when I spin the oil pump with the drill, I get about 50# of pressure and I can see moving around the lifter area but after several minutes I still haven't gotten any oil up into the rockers. I'm sure I have the rocker shafts installed right. I have even removed a bolt from the shaft towers and oil does not appear to be getting up there. The oil is pretty cold. Is this normal and will it get up into the rockers after its started? Has anybody run into this before?
