I just purchased a 1986 Ford F-150 302 EFI.I am looking at going from EFI to a Carb. What all do I need to change out? I assume the intake but im not sure what else needs swapped out. Any help would be great. Thanks.

 

Obviously the intake. Reworking the fuel supply (lines, pump, etc). EEC wiring will have to be reworked to carb operation which will include ignition. Lots of other small adjustments and reworks.

Bottom line is much more trouble than it's worth but do it if you've got the money and time.
