The priming tool has to have the oil gallery crossover at the bottom of the tool for the oil to pressurize the top end.

The cross over can be seen on the image below, it's the blue part in the foreground:

Got it figured out my block is a '66 cast chevelle and they had a diffrent main main bearing with a groove and 3 hole for the oil passage ways to the lifters. We never could get oil to the top after replacing it we hooked up the started and ran it we where able to get oil to the top.
