Just picked up a 67 Mustang Convertible Project car. It is an inline 6. That didn't matter much since I would like to swap out the 6 cyclinder engine and all related items with items of today's technology. I'm not looking for a drag or race car, just a nice driver with some pep, better mpg and smooth riding car. Some thoughts are fuel injection engine with automatic AOD trans, 5 lug rear end, electric radiator fan and serpentine belt system. Possible complete front end with disc brakes, suspension, rack and pinion steering. Some input is to use a ford explorer rear end, shorten long tube side and use shorter axle. ? Should go with rebuilt engine with MSD Atomic EFI or engine with EFI engine from factory. I appreciate any and all feedback to steer me in the right direction.
