A Chevy 305 engine that has been bored 0.040 inches over is commonly referred to as a "305 .040 over" or "305 bored .040." This modification increases the engine's displacement slightly, typically to around 311 cubic inches, which can improve performance. It’s important to ensure that the engine components, such as pistons and rings, are compatible with this alteration for optimal performance and reliability.
A 289 bored .030 over.
its called nothing because you wouldn't have a ENGINE left if you bored it 4" over
A 262 bored 30 over.
A 427 bored .60 over is 438.8572417 or basically a 439.

A Chevy 305 engine bored .040 over would typically be referred to as having a +.040 bore, indicating the increase in bore diameter from the standard size. This modification can increase the engine's displacement and potentially enhance its performance.
The bore adds about 10 cu. inches to make it a 337
A 283 ci engine that has been bored out 0.040 inches is commonly referred to as a "283 bored .040 over." This modification increases the engine's displacement slightly, enhancing its performance characteristics. The term "bored out" indicates that the cylinder bores have been enlarged to accommodate larger pistons, improving airflow and potentially increasing horsepower.

A Chevy 396 engine bored 0.060 over is commonly referred to as a 402 cubic inch engine. This designation comes from the fact that boring the engine increases its displacement, as the original 396 cubic inch engine is enlarged by the increased cylinder diameter. This modification can enhance performance by allowing for greater airflow and fuel combustion.
Sounds like a 343 to me. But for parts its a 283 bored 60 over
