In that case I would have to agree with Del on it, and also think there are better things you could spend your money on.
It would be nice if we all had the money to buy and/or build whatever we want when we want but a lot of us have priorities to deal with.
Maybe just do it like stock but with larger line. (like 3/8)
That would give you decent volume for any engine under 5-600 hp with hardly any added expense and if you needed more later then a different pump (later) could do it just fine.
