Factory cams in all of those. Yeah right. LOL Sure sound good though!
None of those numbers really mean a lot. People blame the gas crunch and lower compression for the huge drop in HP after '72, but it wasn't as bad as all that. What really changed is how HP was figured. Before that, it was gross HP. They put the engine on a dyno, with it's best tune, no filter, no exhaust, no a/c, no alternator, no nothing. You got high numbers. After that, they went to a standard which was based on a factory engine, with accessories, intake/exhaust etc. It naturally results in a lower number. Take a car today and measure HP by the old method and you'd end up with some crazy high numbers.
It's very hard to compare the figures from those cars to today's cars as well as performance. Whatever Motor Trend got from the car when new doesn't tell you what it's capable of by today's standards. They would've picked up a LOT of time in the quarter mile with modern tires, so certinaly 0-60 doesn't mean much unless you take a factory perfect restored car and measure everything by today's methods and modern tires for performance. Handling...maybe a little better due to grip, but the old suspensions and brakes still need updating.

Beautiful cars, but LOL, do they sound like a can full of marbles at low RPM. Performance cams tend to do that when building them. My brother had a 1968 Dodge Charger with a 383 magnum. He only upgraded his carburetor and talk about take off. He smoked a dozen sets of rear tires in couple weeks. Today`s E-cars would blow the doors off all of them.

There's the old way of measuring HP, the new way that measures it at the crank but in consumer form, and then HP at the wheels, each being lower than the previous.
At the crank, my '18 Mustang GT using current methods is rated at 460hp, stock, and that's just the plain old GT, not some special edition. The GT350 puts out 526HP at the crank, and the GT500 puts out 760.
It wouldn't surprise me if transmissions and differentials are more efficient now, and more of that power makes it to the wheels. Of course cars are heavier now, so that will limit the actual performance.

I noticed one flaw in that "formula" right away though... When comparing power via the dragstrip quarter mile times don't matter nearly as much as trap speed. Times are HUGELY (in racing terms) affected by reaction times at the tree. Trap speeds are not. I used to do a bit of motorcycle drag racing (street bikes, not true drag bikes). EDIT: Hah, I should have read the whole article before posting, it addressed exactly what I said: "As a drag racer will tell you, the mph figure is the better indicator of horsepower than ET"

Where my favourite American muscle car is the Challenger R/T A friend had a 351 Mach1 Mustang fastback and at that time I had a 1600cc DOHC Fiat 124 Special T, when he took the car out on to the local straight away and lined up against my little Fiat and then we floored the cars, I watched him in my rear view mirror all the way to the end of the straight. He was not a happy chappie He sat there spinning the wheels and by the time he got moving I was almost over the horizon, the Mustang should have eaten the little Fiat for breakfast but it didn't, that little Fiat beat a lot of bigger and supposedly better cars, and you would never know there was anything special about it, but the engine was one hot twin overhead cam twin twin choke webber carbs and a close ratio gearbox with limited slip diff or the rear, man it could shift, and it had excellent road holding too. Looking up the 0-60 times the Fiat was 7.2 and the Mach1 was 6.1s, so a little difference but not as much as I thought, and there is about a second difference over a 1/4mile, not bad when you compare the 5.7 litre mustang to the 1.6 litre fiat.

I’ve always been infected with a love of cars. Had a couple hot ones. My old muscle car was a1970 or 71 383 Magnum Roadrunner. Then I had several other nice cars like 280Z, Mazda RX-7, Porsche 944, 1984 Corvette, 1989 Corvette convertible, 199? BMW Z3, 2001 Jaguar XK8 convertible (still have). But none have had the excitement of driving as my 2006 Maserati GranSport Spyder CambioCorsa. Fast, nimble, good handling and ride, very cool F1 transmission and shifting, etc. Never had a car that got the head turns and attention as the Maserati. The engine sound alone gets people to turn to see it.
Good people sleep peaceably in their beds at night only because rough men stand ready to do violence on their behalf.
Someday your life will flash in front of your eyes. Make sure it is worth watching.
