OP
you found "gunk" on front of pan. IDK what it was but the note about replacing oil pump may apply more if whatever that gunk was, especially if the PU screen was clogged with some crap, also got sucked up inside oil pump.
You could just open the pump up and inspect/clean and re-use if it checks out. Many put in the GM white spring (HP) in a stock pump
I would get a 1 piece oil pump drive shaft regardless if you still have the stock one with plastic collar and are doing a cam swap
I'm that asshole over here using oil pumps with 250k miles on them and not having an issue, but what do I know?. if the motor had oiling issues, then maybe, MAYBE I would replace the pump. but there's nothing really to go wrong with the pump itself. stock pumps are fine.
JB weld pickup tube on so it doesn't fall off
GM white high pressure spring
Melling 1 piece steel oil pump drive and done.
Those parts will cost you about $30, and guess what, it's what we run in everything. @Ltconvert oil pump is a white spring stocker with 150k on it......and Karl Ellwein put it right in the 383 with nary a hesitation.

I've had good luck with these. The pickup comes welded to the pump. Drive with steel sleeve and mounting stud included.
$50

Lots to address here so I'll do my best.
1st, I think the gunk in the pan was old oil and some road crud that had sat in the seam at the front of the timing cover. It was limited just to the front.
Car had just hit 100k and never had any oil issues whatsoever.
I hadn't planned on changing or modifying the oil pump. I'm running out of funds rapidly on this cam swap and hiding shitbon credit cards to mask the true cost.
Lol
That's understandable. The thought on the oil pump was erroring on the side of caution. I have scene a lot of premature engine failures do to oil pump performance. Looks like others have ran them for couple hundred thousand miles and not had issues. I was giving advice on wanting your cam swap to be with out a problem arising.
Congrats on the cam upgrade hope you enjoy it.
