Street/Mostly Strip Front Suspension

I've cloned my 74 Dart Sport into a 70-71 Duster. As the title implies, it will be street driven, but not much. It'll get used at the track. It should weigh about 3000 lbs. w/ driver. It has a small block, automatic, glass hood, fenders, and bumpers. It has 6 cyl. torsion bars. (About .854" w/ paint.) To start out, it has 6 cyl. leafs that have poly bushings and are front half-clamped, and new stock shocks. Down the road, it'll get Calvert mono springs and Caltracs, with a corresponding shock. It'll probably run mid-high 11's.

I don't want to use aftermarket control arms strut rods or K- member. My goal is to have freedom of movement. I have more time than money. :)

The steering components are tight. It needs lower ball joints, and I'm replacing the uppers while I'm at it. Who makes good ball joints? On RockAuto, I see prices from $13 to about $40.

I'm guessing that poly bushings are the way to go. I'm all but sure I want them on the strut rods and lower control arms , as they handle a lot of the stress. But will they allow for a "loose" suspension?

The upper bushings. Also poly?

My 1980 :eek: Direct Connection book recommends stock front shocks, of varying strength, depending on the e.t. Sounds old school. Without going straight to a high dollar shock (I'll get better shocks when I get the Calvert stuff), what's a good place to start?
