Original 1969 Ford Mustang Boss 429 Unearthed On Ebay


If you wanted to go fast in a Mustang back in 1969, Ford gave you a wide variety of options. On the entry level side was the base 200 cubic-inch six-cylinder Mustang, followed by the 250 cubic-inch six and no less than eight different V-8 engine options.

Atop the Mustang food chain that year was the legendary Boss 429, of which only 859 were built during the car’s first-year production run. Truth be told, these models weren’t even built by Ford, which already had a plate full of ongoing special projects. Instead, the build of the Boss 429 Mustang was farmed out to Kar Kraft.

Building the Boss 429 from a production Mustang was no minor task, since engine mounts, suspension mounts and even shock towers had to be moved to accommodate the 429 cubic-inch V-8. While rated at 375 horsepower for insurance purposes, it’s widely believed that the 429 cranked out closer to 500 horsepower in stock trim.

It was fast enough to propel the Mustang through the quarter mile in the mid 10s, with a few modifications and the addition of drag slicks. To put it in perspective, a stock Corvette ZR1 is only capable of an 11.1 second quarter mile, and today’s fastest production Mustang (the Shelby GT500) takes 12.2 seconds to cover the distance.

The Boss 429 Mustang was built for racing (and to homologate the engine to run in NASCAR), and most were driven hard during their short-but-glorious lives. Finding an all-original, numbers-matching survivor with less than 2,300 miles on the clock is hardly an every-day occurrence, but that’s exactly what’s up for grabs on eBay, found via Jalopnik.

For sale to the highest bidder is a Wimbledon White Boss 429, purchased new in 1969. After the original owner bought the car, it was shipped off to Tasca Ford in Providence, RI, for conversion into a drag racer, and in the 42 years since the car has only accumulated  2,219 miles.

The current owner rebuilt the engine after purchase, and claims that the car will consistently run 10.5 quarter miles at 118 miles per hour. If you want to verify that on your own, the starting bid is $185,000, but even that’s not enough to clear the reserve.

We’d want to do a little background investigation on the car before parting with that kind of money (assuming we had it), but if it’s as good as it looks to be, it isn’t likely to depreciate. There aren’t many Boss 429 survivors left, and this one may be among the best you’ll find.

  1. There's no way those 1/4 mile times are correct. I remember Car Life testing wringing out a (I think '69), and they couldn't do any better than 14.1 in the quarter. Yes, it was fast for its time, but nothing like what's being claimed here. And not much faster than other similar cars in its class. What made the Boss 429 so unique, was its exclusivity: less than 1,000 produced, and understated, broad-shouldered styling.

  2. He said those times were recorded after rebuild, which is possible with some modest upgrades ,like cam, bigger carb and gears. Fords 428 CJ holds record for quickest stock 1/4 mile time for its day. Also Nascars version of the 429 would easily make 500 hp.

  4. Considering the mentality of a GM person that only thinks GM's can run in the 10 second range, when you consider a 65 Mustang with the Kcode 289 and 4 speed would run mid 12's I think the 429 was being conservative in their 1/4 mile times due to HP and insurance because the brake HP was 475 hp is way greater than the flywheel HP I don't see the problem believing these claims

  6. Considering the fact that I happen to have a 66 mustang with a cobra crate 302 and a small B&M blower, yes the K code 289 would run those times. There's more added to this "not so rare" vehicle than what's being shown other than the slicks (the firechicken wheels) and who else knows what. Show us under the hood, and then lets talk about it. Speaking of one who should be careful about what they say when they open their mouth, you sure do trip on your words quite a bit....oh, and our 66 stang... mid 10s all day long, and it's not running on pump gas either, Sunoco Blue.

  7. I drag raced in that era and remember those vehicles, they were extremely fast for the time and dominated nhra classes from s/s thru D/s & the ss/s classes as well. set most class records or index as it was called. That said, the 10.50 claim at 118 ... the numbers don't match. a 10.50 et would run ~ 125mph. A 118 mph would deliver a ~ 11.20et. Relative to a ZR1, if you simply added slicks, that car would run ~ 10 flat or better.

  9. There are more comments in this thread
  10. The comparison by the author of this article of the Boss 429 and the new Corvette ZR1 is misleading, not apples to apples. Put a set of drag slicks and let's say a 4.56 gear (like the 429 has) and the ZR1 will out run this Boss 429 all day long. But that's not apples to apples either seeing that the the ZR1 has a supercharged 376 cu.in. motor. Pit the "stock" Boss 429 Mustang against the "stock" ZL1 427 Camaro of the same era, now that would be (and was) some great racing. Both were racing limited editions. I would like to have both in my garage.

  11. @stephentheheathen, you're correct that the comparisons aren't apples-to-apples, but at least I stayed in the produce section. I was simply trying to give a modern, off-the-shelf performance benchmark that people could equate to.

  12. "It was fast enough to propel the Mustang through the quarter mile in the mid 10s, which remains quite a feat for a production car."

    You're saying a stock Boss 429 Mustang could run 10s? They actually ran high 13s at best. A well tuned 428 Mustang could beat a Boss 429. This isn't speculation, it's been common knowledge since 1969.

    "The Boss 429 Mustang was built for racing, and most were driven hard during their short-but-glorious lives."

    Not exactly. It was built to homologate the engine for Nascar. They built 859 in '69 and 500 in '70. This includes two Cougars and the two Quarter Horse prototypes.

  14. I'm 99.9% sure that I have pictures of this car from when I belonged to the L.I. Shelby club in 1979! I have the owners name at that time. The 7 pics show all the following: Same white paint, under the hood is painted black , same after market distributor, manifold, carbs , fuel regulator, and coil position. The hood could not properly close because of the aftermarket manifold and carbs. It has the same tow tabs, Keystone classics on the front. The gas tank has the same modified sump. The rear of the car was modified to fit the slicks(not 100% sure on this), I think the leafs were moved in. They show the same rims and slicks. OOPS, it has the same 1232 on the window..WoW it is the same car!!! Please email me exislandas@comcast.net
