Enlighten me,
Please grasshopper, seems to me you just load up the cam's thrust washer causing premature wear and use more pony power( which we don't need to do) by using a "high volume" or "high pressure" oil pump. If you have oil pressure problems, a stock Melling or what-not should do the trick without robbing you of the ever-so-hard-gained horse power. You can only squeeze so much through a 1/2 inch hole.
Less you regularly float your valves at 6 grand and need more volume, why ?
...Or am I just too tired, it is 1:44 a.m.
