IF you bought a GTD project car to lower the engine and box then decide if you would lower it so much as to make the sump go below the bottom chassis rails. I would suggest not but some have. But IF you take this as a starter presumption, my suggestion would be to not invert the gearbox but chop the rear chassis off (behind engine) and replace with a Southern GT rear frame specifically designed to lower the engine and box without the need for inversion and also I beleive without the need for a new exhaust system, something often required previously. Not a small job but it is how I would choose to do an engine lowering excercise now having seen various methods employed over the years. Kevin did write an article in the GTD club mag years ago about what he did so if you still want to go down that route, talk to Paul Thompson who has the GTD archive to get a copy.
