If the stock oil pan is used, is there a reason not to use the stock oil pickup? Also, I had read in Tracy's papers about the need to slow down the return of the oil to the pan to reduce the amount of frothing( this was accomplished by the oil pan sandwich plate mounting method ).  Are the anti-frothing methods still believed to be needed?  If so, if the oil pan sandwich plate mounting method is not being used, any suggestions?

Thanx...
