1969 Hurst/Olds 442
This car isn't just a really good muscle car. It is the physical embodiment of the concept of vehicular muscle.
It's FUCKING HUGE. It could monster-truck over a row of mustangs if you put some larger tires on it. It's bigger than some pigfat luxury cars being made today, except instead of safety features and electronic gadgets, all of the 442 is stylized steel, chrome, and angry fucking horsepower. Interior space? I've seen a 500 lb guy fit comfortably in one of these cars.
The engine was 455 cubic inches, SEVEN AND A HALF LITERS. I'm pretty sure the only thing larger than that in its time was the 8.2L monstrosity in Cadillacs. But this thing made 380-390 horsepower and 500lb-ft of torks from the fucking factory. And the sound, jesus tittyfucking christ almighty the sound it makes. You haven't lived until you've heard an Olds 455 rev. You can't just watch the youtube video, you need to feel the soundwaves making the air around your chest pulsate and almost literally take your breath away.
The lines on the '69 are perfection, other years are great too but they got more angular and the earlier ones had retarded headlights. Everything about this one is flawless. The wide grill with two round headlights on either side, split down the middle by a racing stripe. The chrome bumpers that don't jut out stupidly far and actually work with the body. The way the back end swoops up to the roof in one clean curve. The pointed windows behind the two massive doors. The way the fender protrusions are swept right into the body panels and not complicated with creases. The whole car is encompassed by one delicious line that goes from the top of the windshield, down around the windows, to the front, under, back up at the rear, and around the rear window, then repeat it all again in reverse for the other side. The designer of this car should have been awarded the highest honor you can receive in automotive design. Maybe he did, I haven't done any research. This thing is ART.
Now my choice of the Hurst one specifically is all about the style.
Look at that side stripe. Just look at it. Seamlessly connecting the rear bumper, rocker panels, front bumper, hood, and then wrapping up around the window jesus christ it's got better curves than a supermodel. It highlights what I was talking about in the last paragraph in an amazing way. That stripe is like perfectly fitted lingerie on the body of a 10/10 woman. If I owned one of these I'd just stand in the garage running my hand over the fenders all day and thinking lewd thoughts. Then there's the spoiler which is the ideal middle ground between obnoxious racecar and boring modern day. Top it all off with that downright obscene hood scoop, this ain't no ricer shit slapped on from autozone. That engine needs to BREATHE. It sucks down so much oxygen you need to live in goddamn rainforest to maintain the balance in your local atmosphere. A normal 442 looks nice, there are other hoods with air vents that are less ridiculous, but this one says "I came here to lay two stripes of rubber half a mile long and then fuck your wife. You're welcome."
And the Hurst/Olds also came with the "his and hers" dual-gate shifter. They had an automatic tranny, yes, but you could move that bitch over and control it manually to rip mad skids, drag race, or tow your massive balls up a steep incline. And this was the 60's so they still had the balls to imply women can't drive in their advertising. Ladies, stick to PRNDL. Choosing what gear you're in is for the one who brings home the paycheck.
If I had the choice between any supercar on earth with free lifetime parts and maintenance, or a beat up 69 442 with four flat tires and a torn headliner, I'd choose the 442.
