Remember the Challenger Super Stock from SEMA? Yeah, that one. Well, we made an early entrance to Cobo Hall today for Autorama, and happened upon some MoPar sexiness in the form of that same Super-duper Stock concept — oh yes, it's back, and in matte black with gloss black stripes. Otherwise this Chrysler Skunkwerks-designed Super Stock's the same — 6.4-liter fuel-injected Hemi utilizes 10.5:1 compression, twin-plug cylinder heads, forged pistons, a forged crankshaft and forged connecting rods to generate 525 horsepower and 510 pound-feet of torque. The SW engineers made significant changes to the LX platform on which both the original Challenger concept and the production car are based to create the Super Stock. Most significant is the absence of the platform's independent rear suspension. That's right, it's got a live axle, complete with — no joke here — leaf springs. We're told that's to reduce wheel hop and improve straight-line performance. Topping it all off is a set of Mark Williams axles to improve the durability of that back-ass end. All in all, as you'll see from the gallery, it looks even sexier today than when we saw it back in October. We'll have more from Autorama throughout the weekend, so stay tuned to the tag to keep up-to-the-minute.
