You can buy the high volume pump at your local parts supplier.... Melling M55HV
Depends on oil clearances at the crankshaft. If you're under .002", I'd recommend a stock oil pump.

I have the Melling pump on my 409. Works great. Maintains great oil pressure hot.
I used an M55HV on my 348 build, and I found the Sealed Power #2241146 pickup didn't work real well, due to the deeper body of the HV pump. Someone may be able to recommend a different pickup to use. I reworked mine a bit, where it still isn't perfectly parallel to the pan-floor but the clearance ranges from about 1/4" to 1/2", so it should be fine.
I think the pickup should not be parallel to the pan bottom according to the service manual.
