What should it be set at? 40# 60# something else? Are there any downsides to running higher pressures?
I'm a little confused. How do you set it at zero? Take the spring and plunger out completely? Or do you mean jamming the plunger in all the way so it bypasses nothing?
I think that you and Nick are talking about two different things. You are referring to the pressure relief valve that is under the large threaded nut on the front of the lower filter housing. This spring/plunger assembly limits the highest possible oil pressure. That is as long as the oil is warm to hot in temperature.
Thick cold oil can cause higher then the set oil pressure as this relief valve can't pass enough cold oil to regulate the maximum pressure. NOte that the oil that is 'bypassed' via this valve goes back into the pump, not the engine.
The relief that Nick is referring to is the oil filter bypass. This is located in the lower housing where the filter or coolant adapter is mounted. This bypass becomes active when the oil filter can't pass enough oil. The bypass will open allowing oil to skip it's trip through the filter as to not starve the engine for lubricant.
This can occur with cold thick oil, a clogged oil filter, or even a collapsed oil filter.

thanks, 60 it is.60# will work fine for you.
A little bit of a moot point nowI was driving the other day and I started getting a light knock I was 2 miles from home and by got there it was a really bad knock and squeal. I took off the fan belt and I still dad the knock. Checked the torque converter + flywheel bolts which were tight but I can move the crank shaft back and forth at least 1/8"!....and get rid of those stock valve springs. They were tired over two decades ago.
You'll enjoy the top end.
