The Chevy 350 and 327 engines are both small-block V8 engines, but there are some key differences between the two. The 350 engine has a larger bore and stroke than the 327 engine, which means it displaces more cubic inches of air and fuel. This results in more power and torque for the 350 engine.
The intake manifold is responsible for delivering air and fuel to the engine's cylinders. The intake manifold for the 350 engine is different from the intake manifold for the 327 engine, because the 350 engine has a different port configuration. This means that the intake manifold from a 350 engine will not bolt directly onto a 327 engine.
However, it is possible to use a 350 intake manifold on a 327 engine with some modifications. The first modification is to use a set of intake manifold adapters. These adapters will bolt onto the 327 engine's cylinder heads, and they will provide the correct port configuration for the 350 intake manifold.
The second modification is to use a spacer between the intake manifold and the carburetor. This spacer will raise the carburetor up, so that it can clear the distributor.
With these two modifications, it is possible to use a 350 intake manifold on a 327 engine. This will give the 327 engine a boost in power and torque, and it will also improve the engine's overall performance.
