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.

Its a 355 cubic inch
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.
That depends on the components used. It can vary from around 150 to over 1000.

Boring a 396 engine 0.030 inches over increases its displacement by approximately 17.7 cubic inches.
