I'm trying to decide how far back I want to put the custom sheet metal on the underside of the front of the car. The photo below is the underside of a Boss 302 LS. It also has a front splitter which sticks out past the front bumper.
I was originally going to put the sheet metal back to line 1. However if I extend it to line 2 that will go back to the back of the oil pan. I just need to make sure the sheet metal doesn't interfere with suspension travel.
