428 V8 Upgrade: 1969 Ford Mustang Mach 1

The Ford Mustang got its second styling update in 1969 and it was more extensive than the one in 1967. Mach 1 was a new performance-oriented model and fastback production (that’s the only way the Mach 1 came) would increase to 44% of overall output. This ’69 Mach 1 is said to have less than 17,000 miles, yet has been upgraded from a 351 to a 428 V8. Needing bodywork and paint, this running project is in Chandler, Arizona, and is available here on eBay where the current bid is $16,400 with an unmet reserve.

Mach 1 was perhaps just what the doctor ordered to help curtail dwindling Mustang demand. From 1966 to 1968, sales were down from 607,000 units to just over half that at 317,000. But competition was a factor now as almost everyone now had a dog in the fight. Mach 1 would comprise nearly 25% of Mustang production, so while sales dropped again to right at 300,000 cars, the decline may have been greater without the Mach 1.

The seller’s car left the factory with a 351 cubic inch V8, but that’s long gone now. In its place is a shiny, freshly rebuilt 428 Cobra Jet along with a C6 automatic transmission. The car has only had two owners and somehow the auto has only managed 16,000-plus miles, but could it have turned over? Loads of mechanical work have been done, including in the areas of brakes, suspension, cooling apparatus, charging system, and lots of other stuff. The seller is very thorough in detailing all these items, which collectively didn’t come cheap.

Inside the Ford, the interior has been partially updated, including buckets seats that don’t match the rear seat. The seller describes the passenger compartment as driver quality, so you’ll have to determine if that’s good enough or if you want to go further. Whatever bodywork that was needed has likely all been done, so paint is the missing ingredient at this stage. Do you agree with what’s been done to this car so far and would you continue with it or go in a different direction?

    No way it has 16k original miles. I’ve owned 3; probably 216k or 316k.

    Having a 428 is a big plus,better than the 351 it came with.Sure it might hurt the overall value as far as numbers matching.you could finish the car out dressing it up as a 428cj.

    I had a 69 Mach I. It came with the 351 cid Windsor, with the Motorcraft 4300 4 barrel carburetor. I put over 300,000 miles on it. Then my brother bought it, and I’m happy to say it stayed in the family. He and I drove that Mach I on 4 cross country road trips, and it never skipped a beat. But it did turn heads where ever we drove it. Every where we stopped for gas, or to eat a bite, it would draw a crowd. By the time the 80s rolled up, there were very few left on the roads back east, the only ones remaining were out here in the west where no rust could kill them off. So sad. That Mach I has remained in my top 10 favorite cars of all time. A fantastic Ford!

    I see a lot of discrepancies in this car!!! A- I’ve never seen a Mach 1 with the MUSTANG letters on the back of the spoiler, they always had the striping package. B- I’ve never seen a Mach 1 with a “flat hood”, they always had the Cobra Style Hood Scoop. C- I’ve never seen a Mach 1 that didn’t have the “Wood Inserts” in the door panels! Not to mention the Console is missing! A lot of questions about this car! I would need to see the Marti Report! And those wheels look terrible on this car!!! Needs a set of Magnum 500’s!!!!

      Steering wheel is incorrect, 69 had an inner band going all the way around for the horn. It looks like a 68

      My 69 had the Mustang Mach 1 had mustang across the back spoiler. Steering wheel is wrong, bucket seats are wrong, the hood is wrong, where is the wood trim on the door, the back spoiler, the front air scoop, the center consul is missing, hood locks, and probably more. The rims need to be changer for others. How about the window blind?

    Probably not a true Mach 1, but a lot of Mach pieces on a standard car. No big deal to me, just don’t be trying to pass it on as something it’s not, just say it’s a day 2 car or clone and most would be happy with it. I mostly prefer modified cars anyway, so combining the best parts from other models doesn’t bother me. But I agree, those hideous wheels would have to go. Many other wheels like the Magnum 500, Ansen slots, or Cragar SS would look much better IMHO.

    If it’s the low mileage beauty as claimed? The original owner kept it outdoors, year ’round, with the windows down.

    He put headers on it,given it isn’t a real CJ the owner should have upgraded to aluminum heads and intake to save some much needed weight up front.

    Sorry to clue you all in who are complaining about what’s wrong with this car parts wise, but this car is a half century old. Without the numbers matching engine…all bets are off on what’s stock vs after market because it’s irrelevant at this point. You can either spend a ton of money trying to make it resemble what it’s not…or Restomod it and enjoy the car for what it is now. I had a 68′ with a 351 Cleveland I bought for $800 when I was 16, I loved it!

    It’s not a mach 1, it’s just a generic fastback which is why odd parts appear on this car that do not match Mach 1s. Plus it’s already priced way way too high. No vin pics, no under carriage pics, no close up pics of the body. Rust is why. What you dump into a car for restoration is going to be a huge loss at sale time. New motor and power train is the easy part, it’s the bodywork n interior that’s what’s scared the seller off. Pass
