I have heard of a few being done in stock position. I do know that trimming on floor/ back of doghouse is needed to clear bellhousing. I plan on doing a mustang 2 front suspension with triangulated four bar in the rear. All I can do is try. I put one mid engine in a VW bus once, similar to Mopar Ron's setup... If it needs to be mid engine, then I will just build a 408 stroker, and stay stock location.
