Chrysler's SEMA surprise: 392 HEMI Dodge Challenger Super Stock
While in the past automakers have always used SEMA to display the individual customizations that can be applied to their production vehicles, Dodge is doing something different this year. For what it claims to be the first time ever, the company has unveiled a concept vehicle that has been customized specifically for the SEMA show. Based on the Dodge Challenger Concept that debuted at the 2006 Detroit auto show, the Dodge Challenger Super Stock Concept is a one-off concept built to commemorate the original HEMI 392 engine, as well as showcase Mopar's new 392 HEMI crate engine. The new 392 can be ordered in one of three variations: a carbureted version that produces 540 horsepower and 490 ft-lbs. of torque, a EFI-version that makes 525 horsepower and 510 ft-lbs. of torque, and a long block version. While Chrysler's press release doesn't indicate which engine the Challenger SS Concept is using, our bet is on the carbureted version. We'll have more details along with lives shots of the car soon, but for now check out more high-resolution pics and Chrysler's press release after the jump.

Mopar® Celebrates 50 Years of HEMI® Heaven
with Relaunch of Legendary 392

Center Line, Mich. - Next year marks the 50th anniversary of an engine that revolutionized not only drag racing, but the entire automotive industry as well: The legendary 392 HEMI®. Mention the word "HEMI" to an automotive enthusiast and little else needs to be said. Or, perhaps a lot more needs to be said depending on your perspective.
"The 392 HEMI is a legend so rich in automotive tradition that hundreds, if not thousands, of books and accounts have been written about its historical significance," said Chris Cortez, senior vice president – Global Service & Parts, Chrysler Group."
The History of the 392 HEMI
The original 392 HEMI engine was introduced in the new 1957 model year Chryslers and Imperials. It replaced the 354 cubic-inch version of the original HEMI launched in 1951.
Compared with the 354, the 392 was completely revised and improved, with larger valves and ports, a beefier block and crankshaft, and improved bearings. In short, the 392 HEMI, often referred to simply as the "92," was perfect for drag racing.
More than a few racers bolted on six or eight carburetors, slipped in a hotter cam, tipped some nitro into the tank and went racing. Racing legend Don Garlits ran a 392 in his Swamp Rat I at record speeds of over 180 mph on nitro with no supercharger. Garlits also used a 392 HEMI to officially break the 200-mph barrier when his Swamp Rat went 201.34 mph at Atco, N.J. in 1964.

To further commemorate the legacy of the 392, Chrysler Group and Mopar are unveiling a SEMA first: a concept vehicle tricked out just for SEMA. From Detroit's 2006 North American International Auto Show and a year before its production debut, the stunning Dodge Challenger Super Stock with 392 HEMI by Mopar.
"There was really only one vehicle choice to showcase our new crate motor-the bold, powerful and capable, Dodge Challenger," said Cortez.
One of the most iconic muscle cars of the 1970s, it debuted in the fall of 1969 as a 1970 model. Although it was only produced from 1970 to 1974 (188,600 sold), the Dodge Challenger earned a reputation as one of the most desirable of the original "pony cars," with meticulously restored and rare examples today selling for six-figure prices.
The Challenger went racing in its first year and HEMI-powered Challengers tore up the drag strips across the country in the SCCA Trans-am series and NHRA Pro Stock classes. In 1971, a Dodge Challenger paced the Indianapolis 500.
"The HEMI legacy lives on," said Cortez. "But this Dodge Challenger Super Stock concept will no doubt bring that legacy to a whole new generation."
The all-new Dodge Challenger will debut as a 2008 model in calendar-year 2008.
