Here's a thought.... I invested in a Hamburger econo series oil pan , it has allot of features built into it. Trap door baffling to keep the oil in the sump area during hard deceleration, a built in crank scraper and a diamond stripper windage tray and it has notched pan rails which accepts strokes up to 4.50 with steel rods and 4.25 w/ aluminum rods. I paid about $200 dollars for mine which is very affordable considering some of them fancey racing oil pans can run into the $500 to $1000 range with a quickness. I always use one of them oil pump baffles too.
