With regard to oil pumps, most will suggest you run a standard 351C pump (a Melling 84A, IIRC is one such model).
High Volume or High pressure pumps merely rob power, with little gain. Once you start talking about oiling, you will get lots of discussion on lifter bore bushings, etc.
The pump can be "ported" to improve flow, and a minor increase in pressure can be achieved by inserting a nickel (in your case a 10 Franc piece
) under the pressure relief spring. Good luck with the build! There is LOTS of info here on engine builds - Search is your friend.
A word of caution.... You will get a lot of advice that seems conflicting sometimes. So think hard about everything people tell you, but ultimately, you have to choose who is "the rightest" for you own personal circumstances (engine build goals and budget).
