I have a neighbor that is trying to sell me a 77 charger that he bought new. This car originaly had electronic ignition but about 15 years ago he let some no not mechanic change it to the old ignition -point- system. The car hasn't run quite right since. It's slow to accelerate and lacks power. It's a 360 in. engine, automatic on the floor. My question is in two parts, first since the ignition was changed to the point system should the car have different plugs in it then it originally had? Secondly does anyone know what the old points and plugs were gapped at? He says he thinks the the system that is in it now is the system used in 1974.
Thank you for any help that you can offer.

gap on plugs would be .035" points gap .016" same as my 69 Roadrunner with the dual points
the points system and the electronics used the same plugs
only the igntion was different
also circa 1977 there were actually 2 possible different electronic ignitions available...
The computerized ignition (Called either the ElectronicLean Burn or Electornic Spark Control) was the first fully computerized ignition in the USA on US cars...
the computer was mounted to the aircleaner... these were a poor idea and started having malfunctions at 80,000-120,000 miles
at that time they were often deleted to stop frustrating problems...
the other electronic ignition it could have came with was introduced in 1972 for 1973 production models ...
(hence you have been misinformed the points system you have is oler than 1973)
this second style I mention is a great reliable and easy ignition to work with... however these sometimes got deleted by mechanics who were afraid of the little boxes because they didn't know how they worked...
these have a box mounted to the fender or firewall with 4 or 5 wires running to it, a ceramic ballast resister either a 2 pin or 4 pinstyle depanding on model year of vehicle...
my recommendation is find a parts car (1977 Charger with the firewall/fender style module box ignition) get the ignition harness, distributor, ballastresistor from it and convert it back to the reliable electronic system...
FYI Auto Zone sells remanufactured distibutors for these with the vacuum advance for $38 exchange
email me if you need help obtaing those parts

P.S. Somthing many people do not know is distributors as far as the vaccum advance and the wieghts and springs inside were slightly different wieght and strength to make the vehicle perform correctly
so a 360 distibutor for a Duster,Dart etc would be different than one for a Pick up or Larger car which weighed more...
hence placing a lighter cars distributor in a larger/heavier car like the Charger would make it perform poorly too..

Chrysler replaced a lot of the original Electronic distributors with point distributors in 76 and 77 because of frequent module failure.
Point gap: .015-.020 Plug gap; .035 Dwell : 28-32 timeing:(probably) 8-10 BTDC

It probably had the lean burn system on it. Find the right distributer and it will run the way it was designed to
