MuuMuu101's 68 Dart, A Learning Process...

As far as timing and such, you have to start checking all the basic things as if you are starting fresh... rotate the engine to line up the timing mark, pull the cap and see how close the rotor is pointing to #1 or #6 tower on the distributor. I had a 318 once that actually twisted the part of the distributor that inserts into the intermediate shaft! Acted just like your car is doing now; so maybe the distributor did move or something funny.
