440 Oil Pressure Issues..
Yes, YR is absolutely correct, the SM say's "touching" for the pickup. It allows maximum use of the available oil quantity in the sump.
However, from a "smashed pan" point of view it seems logical to me, the more you restrict the open area of the pickup, the harder it will be to draw needed volume of oil up to the pump to maintain a pressure.
IMO, the pan smash also has the potential of compromising the pickup screen. Should the screen allow large enough particles of umbrella seal, gasket material, or whatever through, it WILL lock up the pump rotors. And fact is, locked up rotors won't always shear an intermediate hex. Been that route.
