1970 Ford Mustang Boss 429 - Grabber Blue, Documented, Ready for Concours

1970 Ford Mustang Boss 429

This 1970 Ford Mustang Boss 429 was built on September 16, 1969 finished in Grabber Blue over white Corinthian vinyl. Power is provided by a full numbers matching 429ci V8 equipped with correct four-barrel Holley carburetor and mated to a numbers matching four-speed close-ratio manual transmission. This example was equipped from the factory with Competition Suspension, front disc brakes, the Drag Pack, power brakes and steering, a 3.91 Traction-Lok rear end, and a tachometer. The car stayed with the original owner until 1989, when it was acquired by the second owner, the proprietor of an Illinois body shop, and refurbished after a period of garage storage. The third owner acquired the car in 2012 and had it repainted after consulting with Mid-Cities Mustang and Bob Perkins. In 2014, this Boss 429 was added to a significant Ford collection. It is now offered on behalf with a copy of the window sticker, a build sheet, a Marti report, and a clean Arizona title.
Just 500 Mustang SportsRoof models were built for the 1970 model year with this engine and transmission combination. This example was refinished in its factory Grabber Blue (J) in 2012 and is equipped with a factory front spoiler and a manually-controlled hood scoop painted matte black.
The 15″ Magnum 500 wheels are mounted with Goodyear Polyglas GT tires. The car was delivered new with power disc brakes up front, as well as power steering and the Drag Pack.
The cabin is equipped with high-back front bucket seats upholstered in white Corinthian vinyl with knitted inserts. The door sills feature the Ford logo, and the dark carpets are covered by rubber floor mats.
The dashboard is trimmed with wood veneer, and a Rim Blow steering wheel was a factory option. Instrumentation includes an optional 8k-rpm tachometer and electric clock.48k miles are shown on the 5-digit odometer, a few hundred of which were added by the current owner. The car is equipped with an AM/FM radio and a factory Hurst shifter.
Kar Kraft of Dearborn, Michigan was commissioned by Ford to modify Cobra Jet Mustangs with a larger 429ci V8 featuring "crescent" shaped combustion chambers. It came from the factory with a forged steel crankshaft, forged connecting rods, and solid lifters. Aluminum dry-deck cylinder heads are fitted along with an aluminum intake manifold and a four-barrel Holley 735-cfm carburetor. Photos in the gallery show the C9AE-6015-A casting and 429-specific screw-in freeze plugs. Recently installed new NOS rocker arms at a cost of $4k.
The engine is stamped 0F109085, matching the original build sheet seen in the gallery.
The top-loader four-speed transmission sends power to a9″ Traction-Lok rear end equipped with a 3.91:1 differential. The optional Competition Suspension includes front and rear anti-roll bars. Additional photos of the underside show the slop grey finish and factory-style markings.
The Deluxe Marti Report goes into detail as to how many versions of the model were made with various options, as well as the production dates for this example.
My standard disclaimer/mantra for any car regardless of service or price: The car is sold with no warranty. You are buying a used car. Eventually every car will break, if you find one that doesn't please let me know. I do my ABSOLUTE BEST to describe accurately the shape of the car, but keep in mind it is impossible to discuss every detail of a car for better or worse. We manage private car collections and hope to pass along my passion and fervor for these cars. That said if ever you encounter an issue I do my best to provide advice, direction or even parts if I have them. Please understand that it is a used car and will have minor signs of use. That means please do not expect a showroom brand new car. Please adjust your expectation level to that of a car that however is ready for near any concours. Please only bid if you intend to buy. If you would like to have an Ebay 3rd party mechanic service check out the car I MORE than welcome it. Please have the car checked out before bidding and not after, if you intend to use that service. And please, if you would like to utilize this service, contact me with more than a couple days left in the auction so we can arrange schedules. Please check your local laws and registration procedures before buying. Buying over the internet can be scary sometimes! I get it, because I am an enthusiast too!! For that very reason, I am more than happy to answer every and any question you may so you know 100% what you are buying. But, please ask any and all questions ahead of purchase! It is impossible to list every pro and con of a car, I am not an inspection service, and my description does not replace one! It is your responsibility as a buyer to do your due diligence and inspect the car. All sales are final, you are buying as-is, the sky is blue, etc, etc. Sorry to have to give the boring speech!
Please feel free to ask any and all questions!!
