This Rare 1970 Ford Mustang Boss 429 Drag Pack Is a Numbers-Matching Gem Worth $410,000

That whole 69 vs 70 model year debate is a very interesting one to have, and we can get into it if you’d like.

Here’s the gist of it. If you’re trying to decide between the ultimate Mustangs, those built for NASCAR homologation, it’ll come down mostly to aesthetics. Mostly, not exclusively.

For starters, you’ve got the quad headlight setup in the 1969 model year car, as opposed to the 1970MY variant, which kept only the grille-mounted headlights while adding fins to the outside of the fascia. Also gone were the rear air scoops, while the entire taillight panel became flatter – it used to be somewhat concave.

Another difference is with the hood scoop, which used to be body-color on 1969MY Boss 429 Mustangs. It became black the following model year. Speaking of colors, the 1970MY Boss 429 offered greater choice with the introduction of Grabber Orange, Grabber Blue and Grabber Green.

Last but not least, the Hurst shifter found in the 1970 model year car, as opposed to the regular Ford shifter.

My philosophy is – to each their own. But if you’re a collector, I’d understand why you might gravitate towards the newer model, seeing how Ford built fewer Boss 429 cars in 1970 than it did in 1969, making the 1970MY Boss 429 technically rarer. It’s not a particularly strong argument, but it’s an argument, nonetheless.

Regarding this particular 1970 Mustang Boss 429, it was originally delivered to Joe Cullinan Ford in Marlboro, Massachusetts, and it’s rocking the Drag Pack from the factory, together with a Grabber Blue over black vinyl configuration. It just sold at auction for a sweet $410,000.

Other visual highlights include the front spoiler, dual side mirrors, rear spoiler, rear window louvers, Boss 429 badging, dual exhaust outlets, plus a set of 15” Magnum 500-style wheels rocking F60-15 Goodyear Polyglas GT rubber. It underwent a full restoration back in the mid-2000s, and it still looks excellent to this day. Dare I say, pristine?

In the cabin, you’ll find high-back bucket seats, simulated woodgrain appliques (dash, console, door panels), a Philco AM radio, a floor-mounted center console, the Hurst T-handle shifter, and a Rim Blow steering wheel. The five-digit odometer is showing roughly 28,000 miles. 

As for that iconic 429 ci V8 engine, it came from the factory with a four-barrel Holley 735-cfm carburetor and an output of 375 horsepower. Everything gets sent to the rear wheels via a four-speed manual gearbox. The previously mentioned Drag Pack is responsible for the high-lift camshaft, a modified crankshaft, flywheel, and vibration damper.

Is this really a $400,000 car? Tough to say. But I understand the valuation.
