Before you pull the engine you should take off the valve covers and look for excessive oil leaking. Make sure the pedestal bolts are tight..
If you have a piece of 6" aluminum flashing make a baffle which stands in the oil valley in the head so you can run it with the covers off.
You may want to pull the intake to check the oil plugs under it before you pull the engine.
You have a big leak to have only 2-5PSI. Probably missing a plug somewhere. See video below for location of your plugs. Looks like a plug also under the timing cover.

Usually cracked main webbing will give a really erratic oil pressure that isn't necessarily low all the time but tends to jump around in a weird way. With that said. Cracks from the main up to the cam hole are pretty common on FE blocks that have been run hard in the past. I've found a crack like that in a customer's 427 block.
