Since I got this car running last year as it sat for at least 12 that I know of ,It runs good for a weeks then it starts,the missing a few misfires coughing sputering.I fiddel with the distributor and back on the road.Then I repeat the process again in a few weeks.When I got the cougar I put a regular new OEM timing chain,a new OEM carberator,and a new OEM distributor.The 390 has been camed how much?who knows.Can the (regular timing chain and or the distributor) have anything to do with this or points and plug gap.When I got it all the HP parts were in a box and the distributors gear shear pin was gone.I got it running to cruse locoly.Is THE magor tear down not to far off?

Timing change

Sounds like the gear is turning[pin is sheared] or the gear is being chewed up do to misalignment with the cam. Pull the distributer out and check.

could be

I went and cleaned all the plugs and made sure no wires jumped off and it started up.I loosened the distributor turned it a bit each way hardly any change.So it looks like the next thing to check.Thanks Dan
