2 barrel , 4 barrel, whose got the answer?
Why not swap to a Pertronix brand or knockoff distributor? Ready to run, has the ignition embedded into the distributor, has built in adjustable rev limiter and a simple two wire hookup.
I have used them on several cars. This setup eliminates all the lean burn wiring, ballast resistor, and the Mopar orange and chrome boxes which are kind odf sketchy these days.
Here is one from speedway motors, has a small cap for better clearance, includes new plug wires, distributor, coil and bracket. Click the photo for details.
