Fellow gearheads, there are some cars out there that can cause a stir regardless of brand preference. When they roll across the auction block, people gasp in awe.

The Blue Beast

Mustangs from this era are generally collectible and desirable across the board, however this one is exceptional. In 1970, the muscle car era was slowly winding down, as the fuel crunch era was just starting to set in. Many cars of this era were celebrating their final push before being forced to adhere to fuel economy and emissions standards. This immaculate 1970 Ford Mustang Boss 429 Fastback came with an options list that could make any gearhead drool. This beautiful Grabber Blue beast appears to be a fun, simple Sunday driver at first glance. The average person walking by may just think it is an old car that is a painted a pretty color. However, this car was a wolf in sheep’s clothing. If you heard the engine start, you would know this bad boy was made for one thing – going fast!






Lurking under that flat black hood scoop is a snarling monster that is ready t0 be unleashed. The incredible options list this Boss came with will leave you breathless. Under the hood resides a monstrous NASCAR born and bred, 7.0L Boss 429 V8. That alone should be enough, however it is coupled with a close-ratio 4 speed with T-handle Hurst shifter! Not enough for you? Then add a 3.91 Traction-Lok rear end. Still not enough? Then we add the FACTORY DRAG PACK! Still need more factory goodies? How about factory competition racing suspension, power front disc brakes, and power rear brakes. Now you have a car that is the stuff of legends…on or off the track!’


Boss Trunk

Amazing Car

This car was bought by someone that had money to spend and wanted the ultimate road machine! The 429 was only available in 1969 and 1970, so this is indeed a rare pony. Notice the pictures above, and you will not find a battery under the hood. Why? The factory included an option to locate the battery in the trunk. Why did they do that? There wasn’t much room left under the hood with that huge engine, and weight distribution matters in racing, so they put the battery in the trunk. It was an option only 500 Mustangs had that year, so its not something you see every day!

Specs and Statistics

This vehicle was a pretty rare car, as stated already. Take a look at the specs from 1970, which will tell you just how rare it is.

  • Total Mustang production for the 1970 model year:  190,727
  • 4,353 With this Paint Code
  • 285 With these Paint/Trim Codes
  • 500 With these Engine/Transmission Codes
  • 500 With Trunk Mounted Battery For the 1970 Mustang 2-Door Sports Roof

As you can see, there were nearly 200,000 Mustangs made, but only 500 had the Sports Roof with trunk mounted battery. That alone makes it really rare! It was also one of the few that were this color, without racing stripes, and with this transmission and engine combination.

Boss 429 With All The Goodies

Take a look at the enviable list of options this car has:

  • 429 820-T V-8 engine
  • Close ratio 4-speed transmission
  • Factory Drag Pack
  • 3.91 Traction-Lok rear end
  • Front spoiler
  • Competition suspension
  • Power brakes with front discs
  • Grabber Blue with White interior and Clarion knit Corinthian vinyl bucket seats
  • Deluxe seatbelts with warning light
  • Rim Blow Deluxe steering wheel
  • Center console
  • AM radio
  • Hurst T-handle shifter
  • Magnum 500 wheels
  • Goodyear Polyglas tires
  • Trunk-mounted battery
  • Marti Report

You may also notice that the option list doesn’t include amenities such as air conditioning or a heater. This bad boy didn’t need all that extra weight! I can imagine running an air conditioner would also be a burden for this fire-breathing beast during heavy traffic. These big blocks were made for NASCAR, not school zones. Besides, if the air conditioner is running and the windows are rolled up, how will you hear the beautiful symphony coming from those  headers?

Fully Restored Boss 429

This car is so iconic, I found a car just like it was used as a symbol on a sign here. The restoration process took some time, but it is completely accurate down to the smallest detail. The Corinthian Vinyl Bucket seats in that off-white color really look great with the wood grain and the blue paint! This car was restored immaculately using tons of original, new old stock parts. It has a list of options that make for the most incredible car we at Bryan’s Wheels have seen in a long time.

Boss 429 Fastback Interior

This particular Boss 429 Mustang was built in late 1969 and sold in the summer of 1970. It is likely that the car did not sell quickly due to the fact that this is a BEAST, and not exactly a family car. The options list are a racer’s dream, but not the most comfortable for a daily driver. This Boss 429 was made to be a racing performer, not a grocery getter. It was custom ordered, but the person that ordered it never came to pick it up,

I can only imagine a car with this engine and these racing options wasn’t fuel efficient either. It is likely the miles per gallon rating is probably in the high single digit or low double digit range…..during rainy weather, when your foot is NOT jammed through the floorboard. This probably didn’t help get it sold either. These cars were also pretty expensive, much like a Shelby today, so they weren’t exactly affordable to the average person. Granted, they are worth every penny to their target audience, but that can still hinder sales.

1970 Ford Mustang Boss 429 Fastback Time Capsule

I am glad the car was restored to its former glory, as a time capsule to show everyone in the future what once was. This Boss 429 is an incredible example of what was possible to order from the factory in 1970. I can only imagine what the original owner thought the first time  they sat in those white bucket seats and fired up this beast. You can bet it was a thrill they will never forget!  The original owner likely wishes they still had it, as this car is estimated to be worth around $250,000 USD!
