by Ross Mills

The third-gen Chrysler Hemi, debuting in 2003, packed more punch and less pollution thanks to its coil-on-plug ignition system with two spark plugs per cylinder. By 2009, this engine was flexing its muscles with up to 390hp, aided by variable valve timing and a Multi-Displacement System. The 5.7-liter Hemi was a hit, but Chrysler didn’t stop there—it rolled out a 6.4-liter beast dubbed “Apache,” capable of a whopping 470hp. The Hemi lineup was a powerhouse parade of innovation and horsepower glory!

The ’74 SD-455 was the muscle-bound heavyweight, boasting an engine so strong it could almost bench press the car itself. By ’75, the Trans Am got a facelift with a wrap-around rear window, but emissions regulations were like a diet plan for the engine, slimming down those power gains. Who needs horsepower when you have style, right?
