I've got several books on older Indy cars that have excellent photos of the chassis and suspension layouts that were tried over the years. Most all the roadsters used torsion bar suspension front and rear. Some of the early cars used channel frame rails but most, however, used round tube. Building the frame/chassis would be easy enough but I know nothing about figuring out the spring rates for the torsion bars. I'm sure that information would be easy enough to come by. Schroeder has charts with the spring rates of the different sizes of bars on their website. Plus there are more than a few sprint cars floating around the state of Indiana. Probably wouldn't be too tough to locate a friendly car owner/mechanic willing to give a guy a little advice on where to start.
This one was restored at Gary Bridge and Iron. I had some dealings with the owner in the past - super talented. I'm sure I could get some advice there. Actually, a car like this one is pretty much just like I want to build. I think you can get away without fenders in Indiana. If not, then something like the Bocar.
One of these days.
