I have recently acquired a wonderful F-250 from a 20yr old kid that don't know anything about engines. It has a 351 Windsor in it with serious issues. Just replaced the plugs and wires and put a new air filter assembly on it as he was driving it without one. Not good for the plugs... Here is the problem when I go to start it you have to play with the timing on it on the distributor. How do I adjust the timing to get this truck running as I need it to move with. I don't have a timing light to help with this so if anyone can help I would appreciate it.

Go to the library and see if they have a Chilton's or Haynes manual for the truck. They explain it well.

The first thing you do is get a timing light.Then the manual. Firing order has nothing to do with your problem because you, as you say, can get it to run. Running without an
air filter will NOT affect the plugs in any way but will rebore your cylinders and grind away your pistons as you drive. What is your compression ? What is your valve timing ?
Is your ignition spark orange or purple ? Has the timing chain jumped ? You have to do
some serious testing and trouble shooting and get back to use with real time info.
Everything you hear here will be a guess untill you do some testing and elimination.
Bottom line. If your engine is set up properly you DO NOT have to play with the timing to
get it to run. Is the ignition timed properly in the first place ?
