1977 F350 with a 460 What is the Timing setting?

If it has the 4 cylinder (2.2L) engine, it has a timing chain. If it has the V6 (3.0L) engine, it has a timing belt. The timing chain or belt is located under the timing cover at the 'front' of the engine -- the end of the engine where the serpentine belt is located.

what country?
cam timing?
it's and engine swap. what year engine, ?

SOHC F8A, which appeared in 1977.

so?
what car did it come out of and what year/?

Perfect timing for fuel efficiency and power is 3 degrees before it causes audible valve ping or knock when the engine is hot and under full acceleration up a hill. To get close with the distrib, advance it (turn it) from a retarded position at 2500 rpm until smooth running gives way to slight kicking. You will feel and hear it. Lock it down and road test, listening for the valve knock. Backfire is more associated with retarded timing.

Try this link. This was as far into the diagram list as I could get with the information you provided. You will need to select the Model of the Saturn, Station wagon is not an option, and the next section should be to select the year then it will show you the different diagrams for the Serpentine and timing belts for all motors installed in the vehicle. You will have to locate the actual diagram you need but it will be there.

what type of timing advance does it have? vacuum etc. you need to disconnect advancing circut to complete this task

sounds like the timing is out, the battery is low and the fuel filter may need to be changed. cheers !
