Want to improve ignition....

Not considering the Pertronix?

Flamethrower III + coil. All hidden, ballast bypassed from behind, absolutely no fitment issues. Must run resistor wires, solid core is a no,no!

I have run MSD, Mallory, Chrysler Orange,Chrome and Gold in every fashion. This has been the best. Hot Multispark and Fires on will. My plugs have never looked better. Lost MSD and Mallory on just a few WOT runs. Mopar lasted well but the Pertonix has outlasted them all. Rev limiter built in to boot!

What Pertronix kit are you referring to? I am seeing a lot of different options. Do you have a link?
