1970 Ford Mustang BOSS 429 Apparel and Accessories by Legend Lines

“FordWith the help of Kar Kraft, Ford's special vehicle shop, the new 429 cubic-inch engine was placed within the engine bay of the Mustang. The engine was a single overhead cam Ford V8 with a large bore and hemispherical combustion chambers. It had aluminum heads that created a crescent-shaped, 'semi-Hemi' combustion chamber, one Holley four-barrel carburetor was installed and all Boss 429s built in 1969. Power was stated at 375 horsepower but was more likely closer to 500 hp. Ford elected to create the ultimate ponycar by dropping it into the Mustang. The production process required many modifications, including cutting and relocating the shock towers to create the room necessary to fit the large engine. The battery was moved to the trunk, and a 3/4-inch sway bar was added to the rear axle. A large opening was cut in the hood to feed more air to the 429. The functional scoop mounted on the hood was the largest of any production Mustang, controlled manually from inside the car. Since air conditioning couldn't fit under the hood, it was not offered. The Boss 429 had a base price of $4,087, making it the most expensive non-Shelby Mustang to date. Color choices were limited to just five relatively conservative exterior colors in 1969, although this would change in 1970. .
