Ignition for 360 magnum
Order (free shipping), Install (<2 hours), start, Done. Don't over think it. I just replaced a points system in a BB with the BB kit. Nice quality. What I like is that you get a distributor with a performance curve and you can get parts at any box store to get you home if it fails. If you are worried, but a spare box and ballast in the glove box. Many, many mopars have run this system for years.
