The bore and stroke of a 327 Chevy is 4.00 inches (101.6 mm) and 3.25 inches (82.5 mm), respectively. The engine displacement is therefore 8 cylinders multiplied by 0.5 L, or 4 L total. This engine was first introduced in 1962 as a small-block V8 option for the Chevrolet Corvette, and it remained in production through 1969. It was then reintroduced in 1985 as a performance option for the Chevrolet Camaro and Pontiac Firebird, where it remained in production until 1992.
The 327 Chevy was known for its high power output relative to its small displacement, thanks to its high compression ratio and aggressive camshaft profile. It was also one of the first mass-produced engines to feature fuel injection, which further increased its power output. Today, the 327 Chevy is considered a classic engine, and it remains popular among collectors and performance enthusiasts alike.
