To hold our engine's lifeblood, we chose to use this D.S.S. 7-quart oil pan, which features a built-in oil return fitting bung, something that's especially handy for turbos or blowers requiring oil return to the pan. This keeps you from welding-or worse yet, tapping-the sheetmetal oil pan for a fitting. This high-quality piece fits most aftermarket long- and short-tube headers, offers great ground clearance, and fits the Boss and Dart blocks' big main caps. No modifications are required.
