You have kInd of a curiosity. Stock bore or already at 0.030"-over? Trying to sell ANY 40+ yr-old OEM thin-wall Ford block will be difficult without running a cylinder wall thickness test on all 8 cylinders, at both top & bottom. And as posted, the motor mounts are big-block type so need adapters, and being a tall block, common Pantera exhaust headers will be up too high & may run into the fuel tank heat shield unless altered. Some Pantera guys have done this (more Mustangers, I think) but FMX blocks are rare and not a drop in adaption.
