I pulled the driver side valve cover off and found that I'm missing the #5 intake pushrod. Haven't taken the intake off to see where it went. I guess the lifter popped out and the pushrod went into the pan. I hope to get a better look this weekend. It has a wet sump stock oil system!

Well..... With a lifter missing..... It won't have pressure.
I guess the real question now is...... Why did that happen?

Didn't the OP originally mention something about atunnel ram swap at teh same time as well?
I seem to recall that
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

Definitelly a missed lifter of the bore will drop the oil pressure BTDT. We can't say the missed pushrod will mean a lifter out of the bore ( I have bent some pushrods being out of its place and lifter still kept in place ), but it could be.
With a new oil pump, definitelly needs to pack up the pump rotors with grease or oil, but if it was already running, is not necesary

IMO, the two "most likely" scenarios for the pushrod coming out are.....
-if it has adjustable rockers, the adjuster backed off until the pushrod fell out.
-the pushrods are not quite up to the job at hand, and one of them crumpled under the stress

Before the oil change everything was fine,or so I thought. I had no idea that something was wrong before the oil change. Had oil pressure and the engine was running well. I warmed the engine up before changing the oil and it seemed normal. After the oil and filter change is when I had no oil pressure. This was a routine oil change. I've never had anything like this happen before.

Providing all was well before the oil change as stated the only way I could comprehend this happening is A. the pushrod just happened to snap or bend at that particular time. B. the lifter, if hydraulic may have collapsed enough before oil pressure pumped it back up. I do find it a bit strange and even more so that the lifter jumped out of the bore unless one was winging it which is unlikely. Finding the push rod may help determine the cause.

I found the problem! The lobe is wiped and the lifter is trashed. Must have been like this for awhile. Not sure if it was coincidence that after the oil change that the lifter wore through and collapsed the lifter and the pushrod fell out. New cam, bearings, lifters and pushrods I guess are in my future. Is it worth the effort to pull the motor out or do in car swap of the cam?

The best solution is pull the engine and clean all the debris out of it. There is a lot of metal floating around just waiting to cause problems.
Good luck.

Good luck. Or there is already a lot of metal lodged in the bearings and piston skirts b/c you don't know how long this has been going on. Hopefully it isn't chewed up too bad.
