LARRY'S LEGEND LIVES

Given that the 21st century has seen a sort of return to the roots aspect for the Mustang, it was probably only a matter of time before the Boss 302 made a return. Over the last few years there's been steady and growing interest in the concept of a new-age Trans Am Special.

Classic Car Overview

1970 Ford Mustang Boss 429 For Sale - SAAC Division 1 Gold Award Winner And MCA Gold LMC is very proud to offer for sale this 1970 Ford Mustang Boss 429   The Boss 429, sometimes referred to as the "Boss 9" by blue oval enthusiasts, is arguably one of the rarest and most valued muscle cars from the era. In total there were 859 original ’69 Boss 429s then only 499 Boss 429’s for the 1970 model year. The origin of the Boss 429 was as a result of Ford’s desire to compete NASCAR. Ford was seeking to develop a Hemi engine that could take on the Mopar Hemi boys - the 426 Hemi Charger Daytona and the Plymouth Superbirds - the monsters for Ford to slay to achieve their desire to rule the track. NASCAR required that at least 500 cars be fitted with the competition motor and sold to the general public. The Boss 429 engine featured aluminum cylinder heads, which had a modified Hemi type combustion chamber which Ford called "crescent". The Boss 429 engine used a single Holley four-barrel carburetor rated at 735 CFM mounted on an aluminum intake manifold. All these cars had the Hurst Competition Shifter 4-Speed Manual Transmissions and the Boss was rated very conservatively at 375 HP while actual output was believed to be well over 500 horsepower. Mustangs were simply too small to accept the massive Boss 429 engine so Ford hired Kar Kraft of Brighton, Michigan to modify existing 428 Cobra Jet and Super Cobra Jet Mach 1 Mustangs. Modifications included widening the shock towers and extending out the inner fenders. The mounts for the front suspension were chopped and displaced to create room for the block and exhaust manifolds. The battery was repositioned to the trunk and a stiff 3/4" sway bar was added to rear end to improve handling since the car was now nose heavy. It was also equipped with a 3.91 ratio rear axle with a "Traction-Lock" limited slip differential. In addition, a hole was cut in the hood, and a manually controlled hood scoop was added. Other features included a front spoiler and color keyed dual racing mirrors.  In short, all Boss Mustangs are simply big block power with few options. These very special cars were given NASCAR identification with a "KK" number that was placed on the drivers side door. 1970, the second model year had very minor changes and production was drastically cut back. Changes included the mechanical lifter camshaft and an improved dual exhaust system though rated power output stayed the same. The biggest change were the five new exterior colors – Grabber Blue, Grabber Orange, Grabber Green, Pastel Blue and Calypso Coral.   This Boss was built on September 19th, 1969 at Dearborn and then delivered new to Owen Ford Sales Inc in Vineland, NJ. Open the hood with the fully functional air-gulping Hood Scoop, which were all painted Matte Black in ‘70 regardless of the color of the car, to find the monster Boss 429 engine. The engine bay shows very nicely, correctly and is fully detailed with all the production chalk marks, tags and decals. The numbers matching Boss 429 engine is connected to its RUG 4-Speed Close Ratio Manual Transmission with the mandatory Hurst Competition Shifter. It also came factory equipped with a V Code  3.91 ratio rear axle with a Traction-Lock limited slip differential.   This Boss, representing the rarest production year of the Boss, has received a concours rotisserie restoration.  It looks striking in the rare factory Code J Grabber Blue which has excellent depth and beauty. These cars had just a very plain external identification with only the White Boss 429 decals on the front fenders behind the bright chrome Magnum 500 wheels mounted on Goodyear Polyglas tires. The interior features the white Clarion Knit/Corinthian Vinyl Hi-Back Bucket Seats, which look to the the original ones. Even the restoration of the undercarriage reflects a high level of the quality restoration and the detail taken to have this Boss present as you see it here. Marti Report also confirms the other features Drag Pack, Convenience Group, Clock, Rim Blow steering wheel, Console, Power Steering, Power Front Disc Brakes, AM Radio, Dcor Group, Deluxe Seatbelts with Warning Light, Competition Suspension, Tachometer and Trip Odometer. Documentation includes a Marti Elite report, Original Ford Invoice, Original Factory Build Sheet, SAAC 34 Judging Report with Concours Gold Rating, and a reproduction Window Sticker affixed to the car.   As a result of this cars beautiful restoration it has earned the highest honors including MCA Concours Gold and SAAC Divison 1 Gold. It comes fully documented with original paperwork and still retains its matching numbers engine. Being of this high quality and fully documented, this Boss 429 is a investment grade collector car and perfect for the astute Ford enthusiast. Additional Details: 1970 FORD MUSTANG BOSS 429 -
