This Boss 429 powered Sun Valley is an unsuspecting street monster. Running white-walls and stock hubcaps this monterey seems pretty tame. it’s when you hunker down that you notice that the big block shaking the ground is already passing through double-stacked borla mufflers. next you’ll probably spot the moser 9” and 4-link rear. it rides on coilovers all around with a mustang II front end. The 429 is tucked down and back as far possible with the front of the block sitting behing the balljoints.While these cars are not feather-weights, the firm chassis and lowered center of gravity make this car much more agile than it appears. This glass-top coupe is classy enough to take home to mama, but a true freak in the streets.
