How does the oil get from your .060 hole in the bushing into the slot on the lifter body?
Unless I'm missing something, this really doesn't look like it's going to provide proper oiling on a mopar.
I would much rather see a full diameter oil band on the lifter body, that's getting pressure from the feed hole 100% of the time, then have edge orifices above the band in line with the axles.
On the motors I've done with spray bar oiling, I have one .060 restrictor per side.
.060" should be about right, but it depends on how many holes are in the spray bar, and how much area they have bleeding off pressure.
I had to go from .040" to .060" to get oil spraying at the front of the spray bar, and that was with only four .020" holes in the bar. More holes will bleed more pressure with a given area (diameter).
