My dad and I couldn't believe what this Mustang sounded like from the sidelines. Caught our attention every lap. This was at Road America for the WeatherTech Brian Redman International Challenge. According to the entry list, car 23 is a 1970 Ford Boss 302. Craziest sounding 5.0-liter V-8. Could listen to it all day.
