--To make a F100 go better?


Did the 1979 F-100 offer a 4bbl on the small block? I need to meet calif SMOG so can’t just throw an after market manifold on. Who offered a CARB legal manifold?


@dolphinporsche - From what I am able to find, there was no factory 4-barrel option on the 1979 small block. If it is the original engine, it is likely the 351m which seems to be Ford’s first foray into emissions conscious engines. CARB compliant intakes for the 351m are scarce and I had trouble finding one on a quick search of the top aftermarket manufactures. I am not sure on the cross reference between the 400m and the 351m though, so that might open an option if they do cross over.
