A little FYI, there never was a "stock" four barrel intake for the 318. Chrysler just slapped on the 360 piece. Mismatched ports in some cases and all. lol.
Sure there was, the 66-older poly 318 could have had been ordered with 4 barrel intake and AFB carb....it is different than the later 318 the original poster is inquiring about, but a 318 did come with one :D
