My 5.3 in my 68 sits about 1/2" above the crossmember using a "F" body oil pan (98-02) and the sump is still above the bottom of the crossmember. I used the organ donor 2001 ls mounts and made my own mount brackets to get the engine as low and to the rear as possible. I like to fab things up sometimes. The bottom of the "F" body oil pan is basically at the same plane as my 4l65e oil pan is.

I believe using dirty dingo adapters and 68 style mounts position tilt the motor up in the front from what i can tell looking at many install photos. Nothing wrong with it but my objective was to get it low and rearward with some fab work. The f body pan is the thinnest of any pan out there at i believe 1.25". My steering center link in the straight ahead position is so close i can barely get my pinky between it and the oil pan.

Sticking my head under the front bumper and looking rearward i have no low hanging fruit, even my exhaust is tucked up including my exhaust "X".
