Power stroke is a diesel and there is no timing to adjust.

 

You can adjust the timing of the injector pump....not the distributor though. Wait, diesels don't have distributors

 

i have 3 trucks,2 460's & a powerstroke.......the diesel runs flawlessly,its the 460 i wuz talkin about.

 

What kind of problems has your 460 given you?

 

This is a 90 and timing was really off,perhaps exhaust gasket leak as well contributing to the scenario although unsure as it would be a minor one.There is no marks on the harmonic balancer pulley and actually has a white painted line for tdc.Turned the motor a few times inspecting the pulley for marks and have none.Loss of power being the primary concern.Replaced the distributor a few years ago and has loosened up since it was set then.

 

If that is the case (which I find doubtful as I have never seen a Ford damper without marks) you need to use an adjustable timing light.

 

I honestly thought i didn't have any marks on mine either until i took a wire brush to it and got rid of a lot of the rust, then i took a marker and marked 10* (or whatever you want your timing set to) so it'd be easy to see with the light.
