It is now a 355 CID.
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.

No. They ALL came with the standard 4.00" bore from the factory, whether it was a 302, 327, or 350. If it's bored 30 over, it's been rebuilt at least once.

Displacement of "350 bored 30 over" seems to refer to an engine specification, likely indicating a 350 cubic inch engine with a bore size of 30 over (30 thousandths of an inch larger than the standard bore). This means the engine's cylinders have been bored out to accommodate larger pistons, increasing the engine's displacement. The exact displacement can be calculated based on the new bore size and the stroke of the engine. However, additional information, such as the stroke length, is needed for a precise calculation.

That depends on the components used. It can vary from around 150 to over 1000.
