Decades after Chevrolet ended production of the 327, the engine’s esteem has grown to the point that diehard fans celebrate its legacy on March 27 of every year. Though Chevrolet outfitted some of its best-loved vehicles with the 327 engine in the 1960s, none were more universally adored than the Corvette. Though not the first sports car produced by a U.S. manufacturer, the Corvette quickly earned the title “America’s Sports Car” once it entered the market, and has remained a Chevy favorite over several generations of innovation.
The Corvette already had a reputation as a speedster before Chevy started putting the 327 under the hood. But the horsepower upgrade only bolstered that rep in the ’62 and ’63 models. It was in 1964, however, when the 327 arguably reached the pinnacle of its power, and a notable upgrade to that small-block V8 engine would eventually help that year’s Corvette break an impressive power record.
Said upgrade came in the form of the so-called “30-30 Camshaft,” which was developed by Chevy’s team of racing engineers and provided a massive horsepower boost to the Corvette, so much so that the L76 build could push up to 365 hp. As for the L84 build of the “30-30” 327, it allowed the Corvette to push a whopping 375 hp, making it the first small-block engine to achieve such power. The L84 variant of the 327 would remain the only small-block engine to produce that kind of power for nearly four decades, with Chevy’s 5.7-liter LS6 V8 finally topping the mark in 2001.
