This Grabber Blue 1970 Ford Mustang Boss 429 is Listed for $700k

Among Expensive cars are Mopars with the HEMI 426. However, this 1969-1970 Ford Mustang Boss 429 indicates prices are going way high.

It’s easy to understand why the Mustang is so desirable. They didn’t make that many of them, and the gigantic engine instantly made this car a vintage property. But $473,000 is the auction record for the past five years, which was just set in Scottsdale 2022 four months ago.

However, one dealer, Motorcar Classics out of Farmingdale, New York is trying to convert a 1970 Mustang Boss 429 for $699,900. Undeniably, it’s a beauty in this color, but the price is almost double the market average.

If you ask what makes the Boss 429 so special?, you should know that it was built at the height of Ford’s all-out performance era for one reason only: Ford’s new hemi-head engine homologation Boss 429 for NASCAR Grand National Racing. It was a complete makeover for the Mustang, and the full-size Ford had already subcontracted CarCraft of Brighton, Michigan to do the job.

It was a complex transformation that required moving the factory original front shock pylons and lowering the front ride height. Ford also installed several performance components, such as a four-speed Toploader transmission, engine oil cooler, trunk-mounted battery, 9-inch Traction-Lok ​​rear end, powered disc brakes at the front, and Competition suspension with front and rear Anti-roll bars, telescopic rear shocks.

In total, they made 857 (+2 Cougars) first-year models, but only 499 for 1970. Power output for both years is rated at 375 horsepower and 450 lb-ft of torque. Of course, as with many great engines from that era, numbers are rumored to have been lowered for the sake of insurance.

The 7.0-liter racing engine was based on the Ford 385, but had a forged steel crankshaft and steel connecting rods. For 1970, they used mechanical jacks (versus the hydraulic jacks on the 69) and a modified exhaust system. Although it could handle high revs in a battle track, the 429ci V8 engine was limited to around 6200 rpm.

The Grabber Blue example seller says this car has an original engine with matching numbers, KK (Kar Kraft) #2073, older #KK Boss 429 equipped with an emissions fuel system which is very rare. They added, “When introduced to the market after 41 years of ownership, the 429 will likely be one of the 429 most original vehicles available today and has been inspected and verified by world-renowned Boss 429 trainer Ed Meyer.”

I think teacher endorsement is part of the reason why this is so expensive. Bose 429 prices haven’t been this high since the boom of the 21st century.
