It may end up being like the "chicken and the egg"..... As to which was the cause of the problem.......but I was pretty surprised to learn his lifters didn't have any way to pressure feed the bushings.

But they DO...the hole above the axle is hydraulically feed via the wall clearance between the body and the bore. If it makes the builder feel any more confident you could groove a channel on the bore connecting the two feed holes.

Doug is having luck using the lifter in the same way, with no groove AND the orifice actually drops below the feeding bore while on base circle. I would feel better with a small groove personally. and if you had to bush the block a longer bushing fully enclosing the lifter feed area would help too maintain constant feed pressure. IMO!!! lol
