1970 Chevrolet Chevelle SS 454 LS6: 450 HP

The Chevelle is one of the most well-known classic muscle cars, though the daddy of them all was the SS 454 model. More specifically, the one every gearhead really wants is the rare 450-hp LS6-powered version. The big beauty can hit 60 mph in six seconds flat, and is relatively affordable for such a powerful vehicle.

Expect to part with $109,000 for a good one. It'll be the best money you ever spend, given it's the most powerful classic big block muscle car ever produced.
