I thought that might be exactly what you meant. As best I can tell that series is restricted to original race cars, but it didn't sound like your a little too clean '66 is. In any event, my impression is they keep the rules and race details to the membership - you won't find it discussed out on public forums like this. Your doing the right thing talking to current participants and then the organization people.
There's also a second release title "Super Street".
Ouch on the 'zon price.
It's not that specific on trans-am racing. More like Fred Puhn's How to Make Your Car Handle but focused on mopars.
