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?
