Big block engines dominated the Corvette story for 1966. They first appeared in April 1965 and as such had limited exposure. 1966 extended the big block Corvette story with the introduction of the legendary 427 cu. in. motors. They were bored and stroked versions of the 396 cu. in. 1965 big block motors and were available in two flavors: 390 hp (RPO L36, $181.20) and 425 hp (RPO L72, $312.85). The extra cost for the L72 was justified as it included four bolt mains, impact extruded aluminum pistons, a very aggressive camshaft, Holly 780 CFM carburetor mated to a aluminum intake and a free-flowing exhaust. The K66 transistorized ignition was a mandatory option with the L72.
There are reports that the L72 actually featured more horsepower than the 450 hp that was quoted. The specifications were downgraded to avoid undesirable backlash from safety legislation, but enthusiasts only had to read the magazine reviews to learn what was really going on.
