Reply to "Melling high volume oil pump"

The only reason to go with a high volume Oil Pump is if your engine is SEVERELY WORN. As mentioned it puts unessecary stress on your Distributor and Cam Gears. If you can maintain 10Psi pr 1000rpm it is sufficient. Best use a standard pump but blueprint it i.e. check that all tolerances meets Ford's specifications (I will find them for you) and use a 5w-30 or 10w-40 Synthetic Oil for best flow and optimum lubrication. Flow keeps your Bearings alive.

A rebuild Engine will have no problem keeping Oil pressure at 70Psi from below 3000rpm warm with 5w-30 Synthetic Oil with a standard Pump that is verified for correct tolerances. Btw even a new Pump should be taken apart and checked before installed.
