I believe the 4300D (spreadbore) came out w/ the '71 351CJ mid yr engine & had a higher CFM (750?) than the 4300A (605CFM squarebore). 4300D also saw service on 460 engines.

The best information I have says 715 cfm. The 72 HO intake was aluminum. Chuck

Yup, 715 cfm.. 4300D was fords "autolite/motorcraft" bad boy carb of the time and quite the odd ball..I have my original 4300D still, same carb they used in 73 q codes too...Mine come with a spread bore cast iron intake that only works with a 4300D carb....Carb is in my parts room, but the intake is in storage unit thou.
