I think this is a bit misleading. First, there were no muscle cars after 1974, which is the year Pontiac dropped the SD-455. After that, nothing but 200 HP low compression V8's. Second, the faster cars on that list were tested on bias ply tires in stock form. That slows you down in the 1/4, but it really kills your 0-60 because to avoid wheelspin you really can't even floor it. Most 60's muscle cars, if equipped with gears, slicks, and headers, were in the 13's if driven properly. A JK with 4.10's and a six speed is pretty snappy but it really isn't in the same league as a decent 60's muscle car. All of which is not to over-glorify the old muscle cars, as modern performance cars and even a lot of boring modern sedans are just as fast. And I think even a JK with 4.10's is still pretty snappy.
