What is a 327 engine bored 30 over and stroked?

A 327 engine bored 30 over and stroked is a modified version of the Chevrolet small-block V8 engine. Here's a breakdown of the modifications and what they mean:

Starting Point:

* 327 engine: This refers to the original displacement of the engine, 327 cubic inches (5.3 liters).

Modifications:

* Bored 30 over: This means the cylinder bores (the holes where the pistons move) are enlarged by 0.030 inches (0.76 mm) on each side. This increases the displacement slightly.

* Stroked: This refers to lengthening the crankshaft, which increases the distance the piston travels during each revolution (the stroke). This also increases the displacement.

Results:

* Increased Displacement: The combined effect of boring and stroking is to significantly increase the engine's displacement. The exact displacement will depend on the specific stroke used, but it will be substantially larger than the original 327 cubic inches.

* Increased Power and Torque: The larger displacement results in a larger combustion chamber, allowing the engine to burn more fuel and produce more power and torque.

* Improved Performance: The modifications can make the engine more powerful and responsive, enhancing its acceleration and overall performance.

Specifics:

To determine the exact displacement and characteristics of a 327 engine bored 30 over and stroked, you would need to know:

* Stroke length: The exact length of the crankshaft used will determine the final displacement.

* Compression ratio: This will affect the engine's power and how it performs.

* Other modifications: The engine may have other modifications, such as different camshafts, heads, or intake manifolds, which will further impact its performance.

In Summary:

A 327 engine bored 30 over and stroked is a modified engine with a larger displacement, resulting in increased power and torque. The specific characteristics of the engine will depend on the details of the modifications, particularly the stroke length.
