BF Auction: 1970 Ford Mustang Boss 302

Asking: $60,500Make Offer

First-generation Mustang buyers were spoiled for choice, with Ford producing vehicles to suit every taste and budget. One of the most desirable was the Boss 302, a car developed as a homologation special for the Trans Am Series. This 1970 Mustang is a genuine Boss but has a touch of Tabasco. It is a rock-solid driver that a new owner could enjoy immediately, although they could lift its presentation with a bit of time and effort. The owner wants it to head to a new home and a buyer who will appreciate its potential. Therefore, he has listed it with us at Barn Finds Auctions.

The owner supplies a Marti Report with this Mustang, confirming that this Boss rolled off the line wearing Calypso Coral paint. It underwent a color change to its current Red in 1999, with the car retaining its correct stripes and spoilers. The paint has a healthy shine and should be considered highly presentable for a driver-grade classic. There are no significant flaws or defects, and the stripes only show some light edge deterioration. The panels look to be straight, and the gaps are tight and consistent. The Mustang is rust-free, meaning the winning bidder will not need their grinder and welder. The owner admits it needs a new passenger door skin to make it look perfect but is including a replacement in the sale. The trim sparkles as impressively as the paint, and there are no visible glass issues. The vehicle rolls on a set of Magnum 500 wheels, and the original spare still occupies its rightful place in the trunk. The original owner ticked the box on the Order Form to add Sport Slats, an option that has become more desirable over time. This Mustang retains that feature, and it is in excellent condition.

The defining feature of the Boss 302 was the sweet V8 under the hood. Ford developed the motor specifically for homologation for competition use, and it showed at its best on the track. This engine bay no longer houses that motor, but its replacement is a worthy successor. The 302 has made way for a 428 Cobra Jet of 1969 vintage. It is backed by the original four-speed close-ratio manual transmission that feeds the power to a 4.30 Traction-Lok rear end. The Boss would have launched this classic through the ¼-mile in 15.6 seconds courtesy of its 290hp and 290 ft/lbs of torque. The Cobra Jet churns out an impressive 335hp and 440 ft/lbs of torque. Set those ponies loose, and the Mustang should storm down the strip in 14.3 seconds. Observant readers will have noted this V8 features an oil cooler, which is the genuine article fitted to a Mustang ordered with the Drag-Pak. The owner also includes a significant collection of parts, comprising a rev limiter, a complete and original shaker scoop and air cleaner setup, plus numerous desirable factory components, as pictured in the gallery below. The only mechanical need this classic has is the owner believes it would benefit from a clutch adjustment. Otherwise, the car runs and drives well, and the video clip below confirms that the Cobra Jet sounds sweet and tough.

This Boss might feature updated paint and drivetrain components but retains its original Black vinyl interior trim. There is no wear on the upholstered surfaces and no evidence of UV damage. The dash looks excellent, as do the faux woodgrain and carpet. The only visible aftermarket addition is a gauge cluster mounted under the dash near the driver’s right knee. Console lids are prone to deterioration and physical damage, but the spotless condition of the one in this car indicates the vehicle has been treated respectfully. It isn’t loaded with factory options, with the AM radio providing entertainment on long journeys should the occupants tire of the tune produced by the Cobra Jet. If I were the new owner, I would never fire up the radio because I can’t imagine not enjoying that fantastic bass line from under the hood!  The overall condition means it will cause the winning bidder no shame if they rock up to a Cars & Coffee behind the wheel of this gem.

This 1970 Mustang Boss 302 may not be 100% original, but the updates have been carefully considered and well executed. They take an already potent classic and lift its performance significantly higher. I have heard of enthusiasts who have coveted a genuine Boss 302, only to find that the beautiful engine that is the defining characteristic can reduce driving enjoyment due to the high-end power and torque delivery. A Boss 302 requires effort and concentration if the driver is to extract the best from it, and some people don’t find the prospect relaxing or as enjoyable as they envisage. The Cobra Jet occupying this engine bay produces mountains or torque low in the rev range, requiring far less effort from the driver to achieve excellent performance. However, if they poked it with a sharp stick, it could effortlessly transform its rear rubber into smoke. At the end of the day, this is a rust-free First Generation Mustang with power to burn. Those are excellent reasons to submit a bid.

    It was an exciting era in motoring. We young folk saw the Boss 302s, the hot Z28s, the screaming Mopars and all of that to the point where it was simply taken for granted.

    My high school friend, almost as penniless as I was post-graduation, got a line on a white GT500 in ’74. The car presented as immaculate though without identifying stripes or badges. It had the 428 Cobra Jet and the hood to go with it. My friend and I concluded that it had been repaired after some kind of frontal collision. There was telltale overspray under the hood. We didn’t know enough to care or to look too closely underneath (seemed straight and clean) to rule out making an offer. The person purporting to be the vehicle’s owner wanted $4000 for it. May as well have been four million bucks.

    We might have found a way to stretch our resources, beg relatives to cover our shortfall but we waited too long as the car was sold shortly after we’d looked at it. Easy come, easy go, but it was a thing of beauty to our undiscerning eyes.

    While I’m a purist, I assume if one car added tgedrag pack, if I am not mistaken the DP came with the Super Cobra Jet engine. If that is the engine now installed, that’s even more attractive. GLWTA

    That is a factory oil cooler to the car it came with stock 4.30 gears witch automatically gives it the oil cooler option (drag pack ) from ford. Witch makes it one of the rarer boss 302

    Can it really still be considered a Boss 302 if it now has a 428CJ?
    Maybe pull that engine, sell it, and find / build a 302.

      Or just pretend it’s a “Boss 428” Ford never built, but should have.

    It’s not a BOSS 302 unless it’s a 302 if you know what I mean.

    Polarizing car to some for sure. Interesting that the Hurst T-handle is 90 degrees out of position… would be very uncomfortable to drive, or the owner has a strangely shaped hand! I remember when they came out, we all had to have them, they even had flocked versions in black and gold. They were “cool” but just not great for everyday driving. It’s really hard to beat the old classic white knob!

      I thought that was weird but I didn’t want to bring it up because how is that possible? I had a nice black velvet one that I believe was stock in my 71 BOSS 351. I had a slight cock clockwise so it would be when my hand came off the wheel it would feel more natural but this is just weird.

    At first glance, this car looks pretty good. But to anyone who really knows cars and has spent enough time inspecting them, this car is rough. There was no attention to details when it was repainted, the tailpipes aren’t correct, same with the rear leaf springs setup. Inside the trunk, it looks like they painted over rusted surfaces. And this is definitely not a Boss 302, with a 428 under the hood. My advice to anyone considering this car, you better go over every square inch with a fine eye or you may regret your purchase.

    Big jump with that last bid. Could that be the seller?

      Shortribs was hunting for the reserve, so we removed all of their bids in between to keep the bid history a little shorter. Sorry for any confusion that might have caused.

      I checked their bidder registration, and everything checks out. They are located here in the US.
