100 miles on the pump gear set. I reused the cover, which I assume was original to the truck. Gonna pull the valve covers tomorrow and see if something is amiss with the rocker shafts.

There is a clearance spec in the rave. Mine was at the top end of that. Verify but think it is 0.005” between the gear and housing. Other possibility is you are losing pressure thru your rod and main bearings. Did you verify you didn’t have oversized bearings and replaced with standard size? That would make lots of noise and probably give you little to no oil pressure. The size will be stamped on each bearing shell. Look at the old ones.

So, updating this thread. After fighting off the flu, getting all the cylinders pinned, with the block in the truck (UGH!) and waiting on gaskets, I'm finally starting to put everything back together. Still no definitive answer as to why the oil pressure was so low.
Once I get the bottom of the engine back together and lowered back onto the chassis I'll pull the upper intake and check the rocker arm assemblies.
Also, Dropping the Y-pipe the bolts at the muffler broke. I'll have to replace those and I still need to ground the pig tail ground wires that I added to the front O2 sensors to see if they start reading and the truck will go into closed loop.
more to come......
