My engine builder,Todd...said with me running 7 qts. of oil,in my Moroso 8 qt. pan,that it really wasn't needed,because the crank was a good distance from the oil in the sump,creating very little windage. Also,it would hinder the oil returning back to the pan,more than without the tray! Been running it that way for 6 yrs.,shifting at 6500..trapping at 66-6700rpm!..so far,so good! Randy B.
