The Hamburger's oil pan was modified slightly to fit in the car. The number to remember is 91/4 inches--that is the maximum length the sump can extend from the rear of the pan, or the Camaro drag link will hit it. Headers may also cause a problem if they tuck in too closely, since they may hit the kick-out portion of the pan. We used a set of 17/8 Hedman race headers that cleared the pan no problem. I modified the collectors to use a regular three-bolt flange and added an 02 sensor. If you are going to use this pan, get the pump, pickup, starter, and other pieces that go with it, as everything is designed to work together.
