1967 Ford Mustang GT Mods Hit The Dyno To Reveal Impressive Figures

Posted on


Exactly 472,121 Ford Mustang examples were sold in 1967 and this is particularly impressive considering the current sports car output. Sure, the pony market isn’t what it used to be, but nearly half a million Mustangs in one year remains one of the model’s greatest achievements in its history. Of those cars, 71,042 were Mustang Fastbacks, which represented about 15 percent of total deliveries during the year.

We don’t know how many of these Fastbacks are still alive and on the road, but one of the surviving cars recently hit the dyno to reveal its power. The blue 1967 Mustang GT fastback from the video above is no ordinary car, as it has some significant modifications.

The current owner of the vehicle purchased the car when he was 15 years old in April 1979. He completed the restoration at the age of 21 in 1985 when the Mustang had about 100,000 miles on the odometer. Since then, he’s ridden it for 38,000 miles.

Initially, it had a four-speed transmission but this is no longer the case as there are now newer five-speed manual models. The default engine has been replaced with the 428 Cobra Jet engine, which features many mechanical adjustments to make it more powerful. It starts with an Edelbrock aluminum head and goes down to a special straight pipe exhaust system. So, how many ponies are left in this machine? Let’s take a look at the dyno running and analyze the results.

The dyno run is in fourth gear and output figures show 265 horsepower (195 kilowatts) at 4,600 rpm and a massive 372 pound-feet (504 Newton-meters) of torque at 2,900 rpm. That’s a definite number for an old-school Mustang GT Fastback and we’re particularly impressed by the torque curve, which remains nearly flat from 2,000 to 4,5000 rpm. This is something you don’t often see in modern cars.

This video is from Late Model Restoration channel on YouTube, which has tons of videos of different Mustangs being dynod. We’ve covered a few of them and you can check out the newer and older Mustangs bringing out their full potential in the related links above.
