This striking 1973 Dodge Challenger, originating from Goodrich, Michigan, was meticulously transformed during a decade-long refurbishment by its seller. The car's most distinctive feature is its heart—a rebuilt 8.3-liter V10 engine sourced from a 2006 Dodge Viper SRT-10, mated to a Viper-spec Tremec six-speed manual transmission, adding an exhilarating edge to the vintage muscle car. The Challenger was repainted in red and features luxurious black and tan leather upholstery, offering both power and comfort. Currently active and seeking a new owner, this unique classic is listed with a bid of $30,250.
