Dodge Hemi Dart LO23 Super Stock – Price: $300,000+

As one of the biggest forces on America’s drag strips in the ’60s, Chrysler always looked for ways to improve performance, introduce new concepts, and break records. After years of fiddling with mid-size platforms, Mopar shoehorned the Race Hemi in the smallest platform they could find, the Dodge Dart, in 1968 (via Auto Evolution).

The actual fabrication of this beast was a challenging task. The Hemi Darts were assembled almost by hand using regular 383 Dart. Installing the big Hemi in the small Dart’s engine bay was a challenging and tight fit. But Chrysler engineers managed to produce exactly 80 cars. Of course, none were street legal and all went to racing teams, painted in primer and ready for race decals and stripes.
