I'm trying to put a list together of the most "Bang for the buck" suspension upgrades to a 1973 charger se (see Sig. for info) Please put at top of the list "Bang for the buck" upgrades that are relatively easy to do for a guy with intermediate automotive skills. I don't have a lift but a jack, stands and basic tools. I'm not looking for a track car but an everyday driver with nimble responsive handling.

1973 Dodge Charger SE 400 automatic transmission. Curb weight: 3800 lbs. All stock so far. Goal: Reliable everday driveable warmed up 400 as close to 400hp as possible, then a 470 stroker if need be. Don't protect a feminist when the collapse comes!
