Curious what the angle of the engine/trans is without modifying the tunnel. The 518 is even larger than most transmissions at the rear, and with it pointed down enough to clear the torsion bar crossmenber and floor, it must angle down at quite a large angle.
My 518 went in my Challenger and matched the 727 angle without mods to tunnel. I shimmed it to 2 degrees downward.
Wow, surprisingly good angle for no cutting of the tunnel metal.
