Its not the most powerful muscle car... its only chevys most power muscle car currently produced (excluding the zr-1, which is consider a sports car).
The fact is that most muscle cars have big V8 engines that are built for raw power but the one problem is that muscle cars are heavy which import cars are not but the V8 can make up for it with most going over 400+ HP and there are not that many import cars that can match that, in the end pure power wins the race.

The most famous Buick muscle car was the 1970 Buick GSX. The GS400 & GS340 were also muscle cars. So was the Skylark GS and for sure the 1970 Skylark Stage 1 GS 455 which was a real runner. The Buick Skylark Gran Sport. Starting in 1965 with the 401 cu in (called a 400) 325 HP engine.
Chevy Camaro, and Ford Mustang.
HP - car - was created in 1912.
The Ford Mustang Shelby GT 500 is without a doubt the muscle car classic! The most sot after Muscle Car is the one and only Shelby Cobra. There is no other muscle car that can touch the 1962 Shelby Cobra when it comes to collectibility. Click the link to see the king of muscle cars.
