Original owner BOSS 429 Mustang, not concours, but who enjoys their concours restored Mustang as much as this?

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.
