stock or hv oil pump

You still don't get it. Yes I have seen them. I am not talking about the pickup. I am talking about the PUMP. "ALL THAT" STILL has to go through THE SAME SIZE HOLE as the standard pump.

We were tallking about the suction side of the pump not the pressure side. You are trying to confuse the issue.
If you don't get enuff supply it won't matter which pump you use.
