We recommend checking the truck's underhood emissions label to verify this information. According to the Motor Emissions Applications Guide, a 1977 Dodge 360 with Federal Emissions is required to be equipped with the following smog parts:
PCV - Positive Crank Ventilation. This is the small rubber hose leading from on top of the valve cover to a carburetor inlet near the lower part of the air filter housing. It's used to recirculate HC (fuel vapors) from the crankcase back to the intake. If you're wondering where fuel would get into your engine from... it seems past the piston rings under pressure. The PCV system is very simple but an important emissions component.
EVAP - The Evaporative System is used to collect fuel vapors from the gas tank and route these gases to the intake. Not doing so would release these harmful vapors (hydrocarbons - HC) into the air. So this system is also very important.
Breakerless Ignition System - Advanced technology in relation to the old breaker ignition systems... which performed horribly when points on the contacts began to wear out; causing tremendously high pollution.
If in fact we've got the correct engine emission information... no additional smog parts need to be added to the truck in order to register it in California. Used vehicles are allowed California registration with only their originally required Federal Emissions parts. You'll need to undergo a smog check. We'd recommend making sure the smog technician is able to verify that the vehicle is Federal Emissions certified. We mention this because the California emissions version of this truck has more than a few added emission components, such as a smog pump, EGR, CAT... to name a few.
