Did you do the check-ball mod to the e-shaft? As in got rid of them and put in a Holley carb jet?
Our race engines only have about 15-20psi when cranking because of the controlled leak created by the oil not having to overcome the springs and balls in the shaft. I always pack my oil pumps with petroleum jelly during assembly so they prime right up.
