I found this car on the same block as a few other DOTS honorees, including the '57 Cadillac, the VW Transporter Syncro, and a couple you haven't seen yet.
Hemi blah blah blah, that's all you hear about when folks talk about the '70 Challenger's engine choices. Fact is, the majority of these cars came from the factory with 318s (60%, according to the Standard Catalog), and another 13.4% had a Slant Six. While we think a Slant Six Challenger sounds like a great idea, the "cool" engine options for the '70 were the 275- and 290-horse 340s, several varieties of 383 (290, 330, and 335 horses), the 440 (350, 375, and 390 horsepower), and the one all the car show geeks bore you about: the 426 Hemi, with 425 horsepower. This one obviously has a V8, but there's no telling which one after all these years of possible swaps.
Back when street-driven Challengers and 'Cudas were common, I didn't much care for the look of this design. These days, however, I've come to appreciate the lines of the early E Body.
