volume over OEM pump and these are the units I am considering.
I figure more is better, but if I am pumping more oil, I assume it is going to use horsepower to do it. So should I stick with the +10% unit? BTW this is a performance street motor (no track/strip time) and should be around the 375-400 HP mark with a hydraulic flat tappet cam.
Theres no need to use anything but a stock pump on that build. The best thing you can do is open up and smooth out the drainback holes so the upper end oil can drain back quicker. If you were going to be running excessive RPM's for long periods of time, it may be worth the HV pump. When you use a HV pump, you really need to install a larger oil pan. This is just my opinion for what it's worth.
