stock bore is 4.32 inches, so 30 over would be 4.35 inches
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.
355
3.671 plus 0.030 is 3.701, about 310 cid. Maximum bore is about 3.8583 (98mm).
the answer is 357 ci (and some change).
300/440 can be simplified to 30 over 44.
30% of 440= 30% * 440= 0.3 * 440= 132
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.
A small block Chevy has a 4inch bore. When you bore one 30 what you are doing is removing .30 thousandths from the cylinder. That would make the bore 4.030 or turn a 350cid into a 355cid.
it is a 30 over 350
it would be a 360. if .30 over is 5 cubic inches then .60 over would be 10 cubic inches
