Most Mopar enthusiast will say never install it that way I shoot for making it barely touch or no more than 1/4 inch off the bottom of the pan I use a coat hangar or a peice of 1/8 inch welding rod to push through the oil drain plug to check those clearances on the engine stand with the motor upside down I've been building HiPo(above 500 hp on pump gas) street and drag racing motors since the early 1970 using stock oil pans with that method , that FSM methods works really good on the stock Mopar oil pickups
