Chevrolet 307 V8 Engine

The Chevy 307 V8 engine came along in 1968 to replace the Chevy 283 V8. The engine was used in lower performance oriented family type cars and was equipped with a 2 barrel carburetor. After 1973 the 307 was chopped from the GM line engine lineup.

One interesting fact regarding the Chevy 307 V8 was that it was also manufactured by GM for boat use and sold by the Outboard Marine Corporation as a high performance marine engine. The marine version of this engine produced between 235 and 245 horsepower and even used the same aluminum valve covers that were used in Corvettes and Camaro Z-28s.
