440 Oil Pressure Issues..

Background:
About 2K miles on 440 Build
Driving in traffic oil pressure would randomly go to zero with an accompanied oil pressure light. I'd shut off immediately and restart. Almost always...it'd be fine again.

Symptoms slowly progressed to the point where when I restarted it'd be kinda low...but with a little RPM it would pick back up.

Now...it's basically zero. No bueno.

I'm running aftermarket oil pressure gauge with a light coming from a separate sensor. I have 100% confidence my indications are correct. Two separate systems (both new) from two different sensors (both new)

The LIKELY CULPRIT: My oil pan got SMASHED from hitting something....hell it's hit a few things. LOL. My car is low. I was thinking a cracked pickup tube.

What I've done:. Pulled the oil pan and pickup tube. NO VISIBLE CRACKS that I can see.

Pulled the Distributor and Oil drive shaft. It's intact. Stuck a priming rod down the hold and spun the oil pump. Feels okay to me.

Changed the oil and filter. Long shot...but thought maybe a clogged filter. Nope.

Sooooo....WTH? Maybe I smashed the pan enough to bend the pickup tube to a position where it's starving for oil?? Seems unlikely to me, but who knows?

Ideas?? Oil pump?? It seems they'd go bad progressively...which I guess mine "kinda" did. But when the symptoms started it was rock star oil pressure to zero. ALWAYS happened at idle initially, when hot. Now it doesn't make any difference.

I'm humbly throw myself at the feet at smarter men (and women) than me.

Thanks all,
Jason
