Been searching junkyards for a 351 core motor for a 393 project in my 69 fastback. I am undecided between the mid 80s setup with the powersteering and alternator down low or late model serpentine setup. I will be adding "daily driver" A/C way down the road. any experience with setups that work better than others? better fitment? clearance problems? Converting to granada PS & brakes and cable T5 also
