Flipping thru some older books I see a bunch of interesting oil pump designs that were developed for the SB Mopar engine. Dual entry pickups, lowered pumps, swiveling pickups, deep rotor packages, etc.

But it appears that most of those items all died off over time. Did people determine that the SB engine worked just fine with a standard pump and so all the special pumps went away? Or is there a trick pump that still exists which I just don't know about?

This has puzzled me too.
I have seen pictures of different styles , but about all I see available today is the pick up coming out of the bottom plate on the pump.

a stock pump in a well prepped SB will give you all the oil you need.

no need for anything else

The stock pump is more than sufficient.

Titan.

I got my pump here. These guys go the extra mile to make sure the pump is perfect. I have taken some new pumps apart that had clearance problems with the gears.

That looks good. I haven't heard of those guys before.

I'm a big believer in blueprinted oil pumps, lots of efficiency improvements can be made porting and chamfering the as-cast passages in the pumps and (in the case of the small block mopar) the main cap.

I really like the milodon mopar pumps, they have a more efficient georotor and work really well.

I have a 340 Milodon Race pan that came with the billet pump housing and the "star" style rotor; I can only run the pan because the Rocky has no K-frame obstruction.

Re-work a stock pump and your good...or use someone like Precision or schumans of you dont want to take the time. They simply do it all for you. I have used both in circle track stuff. You can get them to coat some of the parts as well, which is great in the long endurance apps. With drag stuff I just clean up the stock styles ( the quality is now horrible) and debur, clean, radius and open up and then check the operating and spring pressures on my pump tester. It will often find the over pressure stuff quickly, which is a pain to figure out after the fact!...
