I primed it yesterday and saw that this motor only has 20 Lbs. on the drill motor when I see 75+ Lbs. on other motors with standard single shaft rocker arms and the same oiling system work
I have the valley cover off the motor now to change the lifters so I will try priming it first with the oil to the valve covers disconnected to see how much that helps or not luck
I'll make another post later about this adventure, once I get it fixed properly luck grin
On your deal I would, and have since, bought the Crowers solid body Ultra roller lifters after having some of the cheaper Mopar brand solid roller lifters break the wheels in to two parts and screw up the cam lobe runaway puke Buy the best ones you can afford once, now up

Cab, after putting in restricted pushrods my oil pressure was fine warmed up in the pits, but dropped off some during the run, like down to 50 psi with 20w50 vr1. I am still woeking on a fix. I Have a bushed megablock with .060 holes in the bushings to the oil galleys, Isky EZrolls with two holes in lifter body to pick up oil, .040 restricted manton pushrods, and Jesel rockers on 440-1 heads. I shut off the spratbar oiling before the last test.
