I can probably help but I need more info as you neglected to post the important stuff.
What is the DSO code on the data plate?
Engine ?
Transmission ?
Rear axle ratio ?
Is there either a white sticker
or
a red & white decal on the valve covers ?
I need the info off them if it is there.

Speaking from experience, because when I brought my Grandpas 77 F150 from Oregon I was a little worried also. You don't need to worry about the smog pump unless it had one originally. If it didn't then don't worry. What you do need for the smog test is:
1 - Original air cleaner with thermostatic element.
2 - Fresh air inlet hose on the end of air cleaner
3 - Heat tubing to air cleaner from manifolds - Can't remember actual name,
but its on the passenger side of engine
4 - Charcoal cannister
5 - EGR Valve
6 - Valve covers must vent back into air cleaner
7 - PCV must be in place an connected properly
8 - And of course all vac lines must be installed correctly
9 - If it never had cats don't worry but if it did and their gone - Reinstall them
Good luck

Pretty much what the other guys said. To get smogged in California, the vehicle needs to have all of the original stuff as it came from the factory. Me? I have a '76 F250 Super Cab from Washington state that I smogged and registered in California with a Carter AFB carb on it. It has a PCV valve and TAC (thermostatic air cleaner), no evap system, no egr and no air pump. On the 8100 lb trucks with 460's which mine is, the fed emissions equipment was minimal.
