Engine replacement?

[FOMOCO71]

Own a 1971 f250 sport custom that was converted to right hand drive. Had original 390fe mtr but now have a 460 c6 ridgeback.
Any ideas or no of any websites that deal with the problem.... since the mtr weather it be a 390 or 460 big block is origanalLy
off set to the right of the engine bay. I have a problem mine being right hook now even with mtr across as far as poss exhaust manifold
touching steering box wont line up with diff. So driveshaft on angle they had 390 sitting on angle i am trying to get around this.
only way i think poss is to put back to left hand drive but thats a major any ideas much appriciated.I thought of a small block which most right hand
models of this year have. But seems a waste to not use the worked mtr i have this problem is elliminated in the later trucks with rack and pinion
etc.

so to boil it down your problem is exhuast pipes wont fit? you can get a cutom exhaust sytem for it.
