Here's the setup I used for the regular '73 Firebird in my Muscle D Comparison at the Goose Point circuit. It is exactly the same as the one I used for the Formula. I wanted to see the difference resulting from just switching the car body. I managed a 5:19.34 time, about 4-1/2 seconds slower than the Formula. The specs in the garage were identical, but the stopwatch told the truth.

While racing, both Firebirds felt much the same, although this one's back end would step out more readily.
