Need advice on Oil Pump

In my opinion, a stock pump is what you want. After all my years here, many of the "Why do I have this problem." threads are owner caused.

The wheel doesn't need to be re-invented. The wheel works fine the way it is.

I cannot agree any stronger with this. ^^^^^^

I will add, if you forge ahead with the HV pump, make damn SURE you get the hardened Mopar Performance intermediate shaft, or you will likely make a pretzel out of the stock one.

That said, a high volume pump won't hurt anything as long as you get the heavy duty shaft. It won't pump the pan dry. That's an old wive's tale. They do however take more power from the engine to drive.
