our coverage from the Las Vegas aftermarket extravaganza.
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

"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
"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.
