I have a 1980 f150 302 that ran perfect until the distributer came completely apart, then i dropped the DOW rod down in the distributer pulled the motor out and fixed it, I put new plugs wires and dist. on it and now it wont stay timed what can i do?

 

are you sure you didn't mix wire's, check firing order maybe

 

i double and triple checked that.

 

What do you mean "it wont stay timed"??? Tighten the distributor clamp bolt, and the timing shouldn't change.

If it's tight, and the timing mark moves slowly during the timing process (follow the instructions on the VECI label under the hood) but the engine continues to idle without change, then the harmonic balancer outer ring may be slipping on the hub. Pull the #1 plug, use a plastic drinking straw to verify TDC, and then see where the mark is in relation to the scale.

If it jumps & the engine stalls suddenly, then the timing chain may be stretched out, and hopping teeth.
