Chad Wendel’s Mustang was supposed to stay stock. He drove it like that for about a year, but after he sold his other racecar, the itch started and the 2007 Mustang GT shed its street clothes in favor of full race dress. Under the hood is a ProCharged Ford Coyote engine powered by Holley EFI, which Chad chose for its simplicity and ease of tuning. The Mustang competes in NMRA Limited Street competition.
