How many pounds is the pressure relief valve on the DOD / AFM oil pump? Pretty simple question I think - how many ponds is the oil pressure relief valve on the DOD oil pump? The pump is off an L76 with DOD, no VVT.
Can you swap in springs from other oil pumps (LS3, etc) to change the max pressure?

Not sure, but what I do know is that it is also a high volume pump. It could pump too much oil out of your pan unless you're using a G8 8 quart oil pan as well.
Edit, also there is a 55 psi relief valve in the oil pan as well. If you don't plug this, then it doesn't matter what you do with the spring in the oil pump.

Thanks for the reply!
I am thinking about removing the 55 PSI relief valve in the pan and making the recirculation valve built into the pump the only pressure regulator. I don't like the idea of oil being sprayed into the rotating assembly just to eventually fall back into the pan. I would rather have the recirculation valve in the pump return the excess oil directly back to the suction side of the pump where it will not cause aeration issues, oil consumption issues, or sump capacity issues.
With all that said, I think I am just going to go with an LS3 pump that I ported last week. It will provide good volume at idle and hopefully not fall off as badly at 5500 RPMs as a atock pump.
In both of these scenarios I am removing the pan mounted bypass valve AND plugging it!
