With the Pertronix I am getting ~17hg (up from ~15hg) vacuum when the engine is running at idle. So I ganged a good 1~2hg with the new distributor.

I also swear my oil pressure is running to normal levels of my stock gauge - before I'd always seem to be at the 2/3 to near H mark on the oil gauge (especially before warm up). Though I haven't any clue why a new distributor would make a difference with the oil gauge readings. Kind of scares me that the oil gauge reading pattern changed. Though it's not like it is ever reading to the L mark (far left) of the gauge.

Maybe the original (and the replacement) diaphragm had a bleed hole to keep fresh air in there? Yeah, probably not.
