Go with the hi-volume. Better protection at higher rpms. More oil circulated thru the engine is a GOOD thing. Just make sure you run at LEAST a 6-quart (or more) oil pan (deep or low profile, your choice) with a windage tray. I'm not too sure about that truck oil pan's capacity, 5 quarts maybe? Kinda marginal when that 383 "ramps up" it rpms to 6K.
