Ideally, as has been mentioned, you should be running Valvoline VR-1, or something else with a high ZDDP content. ALL diesel oils have now been switched to the new CJ-4 standard, which means they have a low zinc content. The only other oils I'm aware of that have a high ZDDP content are Mobil 1 20W50, some Royal Purple, Redline, and Kendall oils, and pure race oils. You shouldn't run a race oil (like Valvoline's race-only oils) in your street car, however, as they don't have adequate anti-corrosion additives or detergents. They're meant to be run hard and then drained out after every race.

For a filter, I'd recommend the stock replacement Ford FL-1 or a Wix filter. Napa Gold and Carquest's high end filters are made by Wix. High performance filters like K&N and Mobil 1 are also a good choice, but they're overkill unless you run synthetic and use extended oil change intervals. Avoid cheaper brand filters. They really are cheap pieces of crap. Filters like Fram and STP use cardboard end caps that disintegrate, rubber instead of silicone/nitrile backflow valves (if any), bent thin-gauge sheet metal bypass springs instead of a good coil spring, and cheap spot welded center supports rather than a coiled tube.
