Is there any reasons why a high volume pump shouldn't be used on a relatively stock 440




Drag, windage, sucking the pan dry.

You can always put a different spring or put the adjustable setup on a stock pump and have more than enough oiling for a mild 440. Heck, even the bone stock setup ain't bad!
