SBC 283 V-Belt

The 265 ci V-8 was bored out to 3.875 in (98 mm) in 1957, giving it a 283 cu in (4.6 L) displacement. Five different versions between 185 hp (138 kW) and 283 hp (211 kW) were available, depending on whether a single carb, twin carbs, or fuel injection was used. Power was up a bit each year for 1958, 1959, and 1960. The 1957 Ramjet mechanical fuel injection version produced an even 1 hp (0.746 kW) per cubic inch, an impressive feat at the time. Many tout this as the first US-built production V8 to produce one horsepower per cubic inch. Besides being available in the Chevrolet line, it was optional in Checker Taxis beginning in 1965.
