Is it a tall deck 427 or standard? What lifters are you using? I had the same problem in a tall deck, I was using bullet solid roller lifters and the oil holes in the sides never dipped low enough to get into the oil gallery, they recommended that I grind a little trough from the oil hole down to the relief in the lifter where the oil flows by.
If you end up doing this, grind as little as possible or you may have to run a higher pressure pump. You could verify it first by trying to prime it with some old lifters (make sure they are immaculate and don't turn over the motor) if you get oil to some of the rockers then this may be your problem. |

You have to use a tool that blocks the oil galley to the lifters or it will dump the oil right back into the pan. We use an old dist to do this with, that has the gear teeth ground off. Yea make sure it is turning the right direction.

I Have The Tool Made For Priming The Pump. When I First Started I Spun It For About 3 Minutes And Started To Feel Some Resistance But No Oil From The Pushrods. It Filled The Oil Filter. Now There Is No Resistance Any More. Should I Keep Spinning It?

again.....................it will take longer than 3 minutes!!!!!!!
I might take as long as 45 mins with turning the crank a few degrees every 10 mins or so....make sure you have a stout drill....lol |

If the filter is now full and you are still not getting any oil, something is wrong. Maybe a missing cam galley plug on the front of the engine? Missing plug under the main cap? Something is wrong. Pressure is usually built up pretty fast, atleast that's been my experience.
