When I get my block back from the shop, I'm thinking about making a
modification to it to assist in the engine oiling and oil pressure.
Granted, the condition of the bearings did not help the situation but, I do
not want to have a freshly rebuilt engine and no oil pressure. Before I
pulled the thing, I had about 50lbs at startup and it went down to (almost)
non-existant when it warmed up. I do not, however, know the accuracy of the
gage. There are two issues here 1) oiling the rear and front of the engine
and 2) oil pressure due to warn timing cover.

I've found a few pieces of information on how to handle problem #1, but it
is not sufficient. In case not everyone is up on this subject, I've grabbed
this bit of information from a Q&A on the 'net.

11) Engine Oiling:
- AMC V8s tend to starve the rear crankshaft bearings and distributor gears.
The solution is to put a TIG welding tip into a oil gallery plug. TeamRush's
instructions follow: I drilled the left (odd) bank lifter gallery plug in
the front at an angle directed at the fuel pump eccentric and the
distributor gear. I threaded the plug, and screwed it back into the block,
then screwed a 0.024" mig welder tip into it. When the oil pressure is up,
it sprays a continuous stream of oil on the top crankshaft gear.

If this is the thing to do, I'd like to see a few pictures of the process,
if they exist.

For the rear main, I found a kit from American Performance Products that and
I'm going to inquire about to see if I need to have the block machined in a
few locations before it get it back.

For the pressure issue, it is recommended is to check the clearances on the
timing cover/oil pump cover and either rebuild it or replace it. I've
rebuit the oil pump when I replaced the timing set, but some say that is not
enough. Not sure what to do here. I can check the clearance on the one
that I have or should I just buy an aftermarket timing cover?
