Technically it's called a 360 since that's how many cubic inches it now displaces.
4.060 bore X 3.480 stroke = 360.421 cubic inches.
355
its called nothing because you wouldn't have a ENGINE left if you bored it 4" over
A 350 bored 40 over is a automobile engine which has had its displacement increased to 383 cubic inches. This results in more power without needing to purchase a new engine.

A 350 bored 40 over is a automobile engine which has had its displacement increased to 383 cubic inches. This results in more power without needing to purchase a new engine.
A 350 starts out with a 4.000" bore and a 3.48" crankshaft stroke which really only gives you 349.8 cubic inches. (Chevy rounded it up to 350) Your engine which has the same stroke of 3.48 but now is bored .030" over (making the cylinder bored size now 4.030) total size of 355.1 cubic inches or just a 355.
A 350 engine typically has a standard bore size of 4.000 inches. When it is "bored 30 over," it means the bore has been increased by 0.030 inches. Therefore, the bore size of a 350 bored 30 over is 4.030 inches.
Yes. That would be a 350 bored .030" oversize.
It ends up being about 361 ci
4.040". The standard bore is 4.00".
If you bored a 350 0.080 over It would over heat / run HOT. There would be very little cylinder wall left. You can't even BUY 0.080 over pistions.
