Whatever it had when it was sold in OR is what will be required in calif, it goes by engine calibration number, that is on a sticker on the valve cover, another way to get it is to run the VIN number on a Ford information computer, we call this the OASIS SYSTEM. Also check the emission sticker on the radiaor support under the hood.

Charles: What is the harging voltage on the battery? If between 13.6 and 14,2 you are fine. It does affect performance. Second, Has your fuel filter been changed? Turn your lights on and see if it acts up, then off. If it does act up with lights on, Your alt is not keeping up. Fuel filtrts are inexpensive. Good Luck. Oh, The distributor cap and rotor. _Ned_

None. Yes I said it right, None. Belive it or not in 1976 trucks were not required converters, air pumps and could run on leaded or unleaded gas. Man I've been doing this too long and I'm getting old.

How high is the Hydrocarbon (HC)?
new air filter?
Clean carbon off the EGR passage tube and back side of EGR valve.
This will lower the Nox
Clean/ change PCV.
Ran a tank of gas with Lucas fuel system cleaner.
Do a heavier grade oil change right before the test.
Example: if you use 10W30 then use 10W40.
Keep the engine HOT right before the you pull into the smog machine.
