Select vehicles were invited to be displayed in one of several indoor areas throughout the Carlisle Fairgrounds. We spotted this beautiful '69 Mach 1 indoors on Friday afternoon. Larry Payne didn't just swap an '04 Mach 1 engine into his car; he took the best of both cars and made one killer machine. The '69 sports the '04's firewall and floorpan assembly, as well as the '04 Mach's full interior and drivetrain (save for the 9-inch rear he already had). The car now sits on a custom full frame designed and built by Larry. We hope to meet up with him soon for a full feature on his super-sweet Mach project.
