1. History Of The 392 HEMI

The original 392 HEMI engine was introduced in the new 1957 model year Chryslers and Imperials…

…when it replaced the 354 cubic-inch version of the original HEMI that was launched in 1951.

When compared with the 354, for the 392 we can say that it was completely improved and revised, having a larger valves and ports, improved bearings and a beefier block and crankshaft.

In short, the 392 HEMI, often referred to simply as the “92,” was perfect for drag racing.

More than a couple of racers bolted upon six or eight carburetors, slipped in a hotter cam, tipped some nitro into the tank and decided to go racing.

Racing legend Don Garlits ran a 392 in his Swamp Rat I at record speed of over 180 mph on nitro using 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.

One of the most iconic muscle cars of the period of the 1970s, was first shown in the fall of 1969 as a 1970 model.

Despite the fact that it was only produced from the 1970-1974 period (188,600 sold), the Dodge Challenger acquired a reputation as one of the most desirable of the original “pony cars,” with meticulously restored and rare examples which today are sold for six-figure prices.

The Challenger walked into the 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 moved into 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 2007 Dodge Challenger 392 HEMI got its debut as a 2008 model in calendar-year 2008.
