If you are using a hydraulic cam and the rod bearing clearances are less than 0.0250" I'm guessing the stock pump will supply enough lube.
God, that's a lot of clearance! When I first read this I thought you meant .0025" vertical bearing clearance. Then, I thought you probably meant Rod side clearance.
Anyway, you're correct. Any reasonable clearance will not require a hi-volume or hi-pressure pump.
If I remember correctly, Panic gave someone a real whippin' about side clearance not having any effect on oil throw off and loss of pressure. I still like .020"
