Windage tray or not?

Seem to remember seeing somewhere that improperly designed trays could cost power.

I think they were talking about fitting too close to the crank, or openings that are too small.

With your truck pans extra capacity I'd run it a quart or maybe more low whether you run a tray

or not, THIS should reduce windage!.

Don't forget, you'll need different main cap bolts, to run most trays.
