Chrysler’s Hemi engines, the original FirePower Hemi, kick off with a 331 cu in displacement, producing 180 bhp in the early ’50s. Things heat up by 1956 with the 354 cu in engine, cranking out 340 bhp, while the 392 Hemi in ’57-’58 dazzles with up to 390 bhp, thanks to a rare Bendix fuel injection. Meanwhile, Desoto’s engineers play catch-up with their own Hemi, peaking at 345 bhp in 1957. These engines are powerhouses, proving that Chrysler knew how to bring the heat, with a sprinkling of humor on the side!
