No need for a high volume oil pump, especially for a street/strip car. I have always used a standard pump, and several times, I have installed the high performance spring that comes with the pump. Never had a problem with oil pressure, and I have built several engines. The standard volume pump is more than adaquate. Here is a quote from an engine builder (performance and street) in Long Island, NY.
Now as to your question, we personally use no HV pumps in any street units UNLESS they have aluminum rods. It "stresses" the timing chain, it's tougher on the cam/distributor gears (moreso with the bronze setup), and it does take away a small amount of power from the unit. Probably not measurable, but true nonetheless. Thanks, Gary in N.Y.

P.S. I'm going to add this here but it's a debatable issue. The HV pump contrary to legend, MAY pump the oil away from the screen quick enough to cause main bearing damage. We use to say it would drain the pan. Splittin' hairs, whether it drains the pan or simply takes the supply away from the screen long enough doesn't matter, we repaired a bunch of front mains over the years from lack of oil. We installed the standard M77 pump with the same(M77020) spring I mentioned above and cured the problem. It basically only showed up with stock 4 quart pans. I'm not gonna argue this one!
