when i set out to build our pans, a deep pan with a turned down edge to allow the oil to run down and a small round fence to keep the oil around the pickup that has been relocated to the bottom of the pan. add a a scraper to the side and finish with a mesh screen on the back 4 mains. 8 qt minimum, check the dipstick to calibrate. easy, just need a mig welder, a sheet metal shear and brake, and some talent, and voila! saves the motor, too. our new engine has a milodon swinging pickup and an external pump and is fed through the filter outlet, thank chrysler!!
