Mopar circle track question

This will be a B Body because of the rules, (has to be 112" wheelbase) if I do this. I know what you mean about help. It looks like I would be a one man operation for the most part. Everyone is too busy with kids. I'm still not sure I want to pursue this project, it might be just too much work to keep it going after a while. This will be a pure stocker, I think I would be able to keep up with it as long as it dosen't get tore up bad every week. I have lots of air tools so I am able to fix em pretty fast. Do you think a longer wheel base like a charger would be competitive with the GM metric frame chassis?
