rule of thumb here anything under 400 ci adds 5 cubic inch per .03 over bore. at 400 and over cubic inch, every .03 overbore adds 6 cubic inch.
heres a formula
bore X bore X stroke X number of cylinders x .7854 = cubic inch
427 chevy
4.25 bore
3.76 stroke
=426.72 CI
A 289 bored .030 over.
its called nothing because you wouldn't have a ENGINE left if you bored it 4" over
a BOSS 414!
A 427 bored .60 over is 438.8572417 or basically a 439.
A 262 bored 30 over.

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.
it can be, but Ford made the 429 in 1968-73. There was the standard 429, Cobra Jet, and the Boss 429 built in 1969-70. Most parts are not interchangeable. The Ford engine was not a bored 400.
The bore adds about 10 cu. inches to make it a 337
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 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.
