The person to contact on here would be BBV6 (Pete C.) as he has done this engine switch. From my experience on these motor swap/improvement would be a 351 of some version - far easier and less expensive with a good improvement.
that would be the idler gear mount and return to a roller chain. While a 401 has to have this done as well, the flywheel is a direct bolt up on the 401. The 478 will have to have a special flywheel made for it.
