The motorcraft and autolite carb with the square (not spreadbore ) baseplate is refered to as the 4300A. As far as I know there were basically two sizes of these carbs, a smaller version that came on the 68 302 and 69 351w engines and the bigger version that came on the 70-71 351c and 68-75 429-460's. I also heard that the AMC's had some of these carbs on their engines. I ran one on my 70 mustang in SS and it is very touchy carb to mess with, a real pain.
