To be honest, I own a Supercoupe because I like the way it handles. It's not now and never will be a powerhouse. In all actuality, the 1970 Barracuda I had with a 318 in it was probably around 270 HP...just guessing. That would make it the most powerful car that I've ever owned. I didn't have any money to spare in the early 80s to grab one of these older Mopars, Pontiacs, Oldsmobiles or Chevys when they were able to be had. I was overseas playing soldier for a meager wage less than $10K/year. When I got out in '86 I had even less money raising two children with my wife on a single salary. It wasn't until the 2010s that I had disposable income but no time to spend it because I was working all the time, either for somebody or for myself developing my homestead. Now I'm 62 and blessed to not owe anybody anything except property taxes, but I don't have much disposable income. I completely missed the musclecar era and I'm not very likely to get the chance to participate.
I fell in love with my first Cougar...a 1995 V6. Strictly a GM person for the previous 18 years. Owned it for 6 months, then I wrecked it. First accident in 20 years. Insurance paid because I financed and I bought a 95 V8 Cougar. 4 years later I bought my SC and I was happy to have a 5-speed. To me, I'm pretending that these cars are musclecars, even with modern NA V6s surpassing the power of our dinky 4.6 V8s. My wife's 2016 Acura RDX has 270HP...supposedly. It's quick, but it doesn't feel like SC quick to me.
Anyway... I'd still like to have a 1971 Hemi 'Cuda. They aren't unobtainium but depending on the options, they ARE six-figures, all day long. I could NEVER justify that kind of expense. Much too extravagant for the lifestyle I lead...
Edit: just looked up the numbers for a 1970 318 CI V8. Until 1971 HP numbers were measured without accessories... wonder if that includes the water pump...hmmm. Anyway, they were 230HP at 4400 RPM, 340 ft.lbs. torque at 2400 RPM. Accessories would rob some of that, I don't know how much. So actually, the numbers are very similar to a pre-1994 SC. 94/95 would be just a tiny bit higher. Interesting.
