Well there is several options.
I know that a melling HV oil pump with a Indy cover has the ability to move enough oil to 8K in larger 560+ cid engines.
Go with the Indy pickup also.
I ran a standard HV melling pump and a Indy Pump cover (this avoids buying a different intermediate shaft also) supplying one line, and the aftermarket blocks have a boss near the timing cover to go to to provide the other line for a duel line system, without the center piece used on the milodon pumps which some people hate due to the green gasket failures.
I dont see no reason that a single line static pickup or swinging pickup running just the Indy cover would be more than plenty.
Milodon pickup Vs Indy Pickup
Either way I suggest a Oil accumulator for the best insurance available.
