    Hydraulic lifters. I just pulled the intake off and removed all the lifters. I ran the oil pump with a drill, not getting any oil to the lifter area.

    Do you have a distributor housing in place? The housing actually closes a huge leak in the pressure oiling system......The only other thing I can think of is the two plugs in the back of the block. If they're too deep/too long, they could close off the passages.......Ray

    If one of the rearmost valves on each side were open the lifter would restrict the oil passages enough to cause the problem. Did you try turning the engine over 90* a few times while you were priming it.

    The lifters/rockers do not oil from the cam bearings.....The cam and mains are tied together. The lifters are oiled by the galleries running from back to front, and then up the pushrods, to the rockers......Ray

    Your oil pump drive should be a old dist with the gear ground off, run by a drill. No dist, no pressure.

    Why not just drive the roll pin out and save the gear?......The top of the shaft needs to be ground/turned down to fit in a drill, but the gear is easily removed....Ray

    The inside of the gear is what keeps the oil pump shaft and the dist. shaft centered, without the gear it would wobble apart.

    Well I guess you learn something everyday......Although, I've been using one without anything down there for decades without any problems.....There is a bushing in the bottom of the housing that keeps it lined up......Ray

    The thing you call a gear wrap holds the shaft to the oil pump, then the distributor sits on that shaft silly.
