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.
