Well, not a mustang but if you would consider a '64 Falcon Ranchero, YES. AOD's can be built strong, no problem there.However if you run a carb, get one from an early car WITH ALL the linkage to the carb AND ALL linkage to the shifter. Then cut out about half of the seat support for clearance, fabricate a new trans mount with emergency brake cable support, shorten the drive shaft, rig cooling lines, VERY CAREFULLY adjust the throtle pressure cable (so you don't burn it up in 10 miles) and ENJOY!
