This is really beside the point. This isn't about showing an all-original car, this is about the claim that a 4.0 L Mustang is faster than a 440 Challenger or other muscle car. By restricting the tires, it limits the ability of the car to get traction. If you really wanted a fair comparison of 0-60 times, then at least allow similar tires. While the judges at a car show may not allow radials to appear on an original muscle car, it would be wholly unreasonable to claim that a modern car is faster simply because you were unable to buy modern tires for a car. They don't even have to be drag slicks, just a good, stock radial. If the 440 Challenger, or other muscle car, were a daily driver, nobody would put 185-R14-78 bias plies on it! Putting modern tires on an old car is hardly "modifying" it. Bottom line, when the 440 Challenger gets traction, the 4.0 L Mustang is toast.

You can throw a set of updated radials on your old muscle car and it will make a huge difference in the way it hooks up and handles. This would not disqualify you in most shows for showing as stock.
