In 67 you could get either an AFB or a Q Jet depending upon the application. GTOs and F bodies with 400 engines used Q Jets, full size cars and 326 4 bbls used an AFB. The AFB is of course the square bore base. 65 and 66 intakes are also square bore and will fit the 67 engine.
428 engines, if I remember correctly, also used the Q Jet in 67. Most of the high performance engines were using the larger carb Q Jet, while all the standard 4bbl applications used the AFB, except for the 326 HO. The AFB suited the smaller engine better.
66 4 bbl intakes were all square bore AFB intakes and will fit the 67 heads. By 68 all 4 bbl intakes were spread bore for the Q jet. In 68 the 326 gained 24 cubes and the 350 engine received the Q Jet for 68.
