And the combination would be very cool. I often thought of going this route as I have a primo 66 Coronet 4 door that I used for parts for my 66 Hemi 500. Now, not sure what to do with the body, I thought of building it up for FAST. The weight wouldnt be the problem, as the 4 door cars are about the same size and weight as the 2 door cars in these models. I believe the wheelbase is the same.

This particular car probably wouldn't be the best choice if you really wanted to build a "max effort" entry because the aerodynamics suck and more importantly it has no fresh air hood and the 14" narrow tire is a negative as well. But the rear overhang is good and the Hemi is such a good package for FAST(in fact it's probably the most lethal-maybe the L88 Vette is better??).

So even if it wasn't the best choice of car, with a sorted out FAST hemi, you would be able to very competitive with it!
