Cool or Ruined? Original Owner 1970 Ford Mustang Boss 429 Street Machine!
Heavily Hot Rodded, Original Owner Boss 429 Mustang: Seen in the Barn Finds section at the Muscle Car and Corvette Nationals was Keith Clark’s flared Boss-9
For the last few years, the Muscle Car and Corvette Nationals (MCACN) show in Chicago has had a special section for “Barn Find” cars. Organized by Ryan Brutt, the barn finds area is always among the most popular exhibits at the show, and this year was no different. Across from a custom ‘70s-painted Plymouth Superbird and the “Lee Harvey Oswald ’55 Chevy wagon” (interesting story there) was Keith Clark’s Boss 429 Mustang, which grabbed our attention for obvious reasons but also because of its radical fender flares.
A true “barn find” car is one that is uncovered from decades of hidden neglect by automotive archaeologists who find the car on a rumor. Keith’s Boss-9 is not one of these barn finds as he’s the original owner, but the fact that it was so heavily hot rodded back in the day, and left that way, qualifies it as a survivor.
Those semi-crude fender flares in the rear cover 15-inch-wide Hoosier tires, which Keith said, “some kid once wanted to know if I ‘made those tires.’” He claims the wide rubber is necessary to control the estimated 500-plus horsepower from the 429, which has a custom cam of unrevealed specs. When we walked around back we saw what he meant by his “Quiet/Loud Exhaust”—there are 4 pipes, two with cutouts controlled by what looks like pneumatic cylinders. Oh yeah, there’s a trailer hitch too!
Keith said, “It’s never been restored, it’s driven as much as possible, and all of the work on it is done by myself. It’s a rude, crude, obnoxious attention hog!” And it’s perfect just the way it is, Keith.
