1976 Ford F250 Emmisions

I have a 1976 Ford F250 with a 390 CID that my wife bought in OR, and we live in Ca and have to smog check it. However there is no smog equipment on the truck. Does this vehicle require a catalytic converter and a smog pump, and where can I get an emission hose diagram for it?

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.

Wondering what a1976 ford f250 needs for smog

a lot especially if its california certified.the emmisions label under hood will list all equipmentrequired as well as the vacuum hose routing. if label not available you will need to know engine size/trans type/high or low altitude/ca. or fords have calibration codes that split the previously mentioned options into several sub groups. so that little sticker under the hood is essential.

1973 ford f250 trailer special. new alt. wont

That would be my first guess,they are not very exspensive,if this still does not help,run a large wire on the back of the alternator with the old one still connected,to the positive battery post.This will increase the voltage to the battery also.Put it on the large batt,connector on the alternator,and run it to the battery post+

I have an 87 mustang gt,can the thermactor system be disengaged without causing harm to the engine or anything else, I live in San Antonio and vehicles are not required to be tested for emmisions so...

other than being illegal if yes all of that can be bypassed. Remove the smog pump and lines and plug the holes in the back of the cylinder heads with pipe plugs. remove the vaccume lines for the themactor silinoids and plug any off going to the engine. then you can go order a shorter belt and no more smog system. it was installed to reduce carbon dioxide emissions.

I need to know what smog equipment the 1976 ford F250 had on it to pass the Ca smog requirements

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.
