This is my 1972 Mach 1 mustang that me and my dad restored as a father/son project while I was in college.
The car originally had an H code 351C however we upgraded a few parts like swapping out the 2-barrel carb for and edelbrock 4-barrel carb, high compression pistons, dual exhaust, an upgraded cam, and a number of other tweaks to increase the car's pathetic 70's factory output of 180HP. Though we kept as many original parts under the hood as possible, including the factory AC unit.
Now as far as how much the upgrades have improved the cars performance, we can't say exactly. But we think it's running closer to 260-300, Funny thing is that for some reason we have just never gotten around to putting it on a dyno to find out exactly. (yet)
But either way, we know it has improved cause the car drives great as is, and while not a superpowered drag car. It definitely has a bit of power when you put your foot down and does fine on the highway,so it is still a great cruiser and of course being a bit of a rare car compared to your normal 60's stang, always gets lots of attention at shows and just driving it around town.
And also of course given the color it's not that surprising either. The color is actually the original color of the car (though we found it w/ a crap maaco type red spray job) and is called gold glow metallic which was a special order color from Ford in 1972, and while I never liked gold cars before we got it, I definitely like it on this car.
As for what's on the inside it is mostly stock if not still original w/ things like the original rear folding seat (which is apparently pretty hard to find aftermarket) and the stock Philco AM ONLY radio.
Underneath is original too, down to it's 3-speed FMX auto transmission and the original 2.74/75 gearing on the rear axle.
Though while the original wheels had hubcaps (3 different kinds when we found it) we swapped them out for your standard set of 16" mag 500's w/ a small 2 inch width difference between the front and rear.
The car is definitely a cool car to drive around, and definitely a bit special since you don't seem many of them around these days, at shows or otherwise. But it does seem like they are starting to become a bit more appreciated these days than when we first got it.
And that's as true w/ me as anyone. I originally wasn't a big fan of them but given how expensive 60's stangs were we really didn't have much choice w/ our budget. But now w/ it done and having had the experiences I have had w/ it, I cannot really see myself w/ any other classic stang, and am actually really glad we didn't go for your usual 1 of 10 million 60's stang in the end....no offense to 60's stang owners of course,lol
