For a couple of quick dimension references:
From the block's pan rail (including the factory gasket/windage tray in place) to the outside, bottom of the front of the pan is 2". This 2" section goes back 5 1/2" from the front pan bolts (in the timing cover) before starting to slant downward toward the sump. At the back, the outside, bottom of the rear sump is 6".
