How do u reset timing of distributor after replaceing it. on a ford e350 94'

I have a 1996 f 250 with a 460, i replaced the distributor how do i re-time it

FIRST BEFORE REMOVING DISTRIBUTOR YOU NEED TO HAVE ENGINE IN NUMBER 1 FIRING POSITION AND THE CRANKSHAFT PULLEY MARK SHOULD LINED UP TO 0 DEGREE ON THE TIMING SCALE ON THE TIMING COVER. BEFORE REMOVING DISTRIBUTOR YOUR DISTRIBUTOR ROTOR SHOULD BE POINTING TO THE NUMBER ONE FIRING POSITION AND NUMBER ONE PISTON AT TOP DEAD CENTER.

You will need a timing light....Start the engine and allow it to warm to normal operating temperature....disconnect the vacuum adavance--then slowly rotate the distrubtor while using the timing light to set it.
The timing mark for top dead center will be on the harmonic balancer, the pointer will be attached to timing chain cover, Set the timing as follows per engine size.
5.0L- BTDC 10° ± 2°
5.8L- BTDC 10° ± 2°
7.5L- BTDC 10° ± 2°

Turn off the engine and tighten the distributor bolt. Recheck the timing to verify that the timing did not move while tightening the distributor. Replace the shorting bar or vacuum line.

I hope this helps,
