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.

GM, per the 1966 brochure, was rightfully proud of the four wheel disk brakes which first appeared on the 1965 Corvette.
Corvette C2 seating was quite comfortable, definitely more so than the C1, and, some would argue, better than the early C3 seats.
Drivetrain choices were nicely varied in 1966. Notice the number of axle ratios available, quite a contrast to later years when regulations would effectively limit the number of options. The "Not recommended for general driving" refers to the famous M22 "Rock Crusher" Muncie four speed transmission. The M22 was exceptionally strong but, due to its straighter cut gears, had an audible whine.
GM was always proud of the "Bang for the Buck" aspect of the Corvette; it would be a constant theme in their marketing efforts. Below: 1966 Corvette convertible on display at Carmel-By-The-Sea California.
