Ford F150 351 (5.8L) - What smog parts are needed to be legal in California?

1979 Ford F150 4x4 351 (5.8L) 6500 GVWR. What smog parts are needed to be legal in California? New to CA, and I am trying to find out EXACTLY what emissions components will be required for this vehicle for a CA smog test. The emissions sticker on the valve cover is gone. I do know from the VIN that the truck was originally sold in the St. Louis, MO market. Does this make a difference? Right now the vehicle has a 4 barrel carb, aftermarket intake, and true duals with no CATS - I'm guessing not legal in CA. Thanks.
Answer:

According to the Motor Emissions Application Guide, your 1979 Ford F150 is required to be equipped with the following emission components whether built for California or 49-state emissions: 2 Barrel Carburetor, PCV (positive crank vent), ACL (pre-heat duct), AIS (smog pump), EGR (exhaust re-circulation), EVAP, and CAT (catalytic converter - Type OC). As far as aftermarket emission components.... California will consider any emission modification an Emissions System Tamper, unless the components instaled posses an EO (Executive Order) number indicating the component was sold legally in California and is approved for California vehicle use. posted by SmogTips Support
