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.
4.040". The standard bore is 4.00".
No a 383 is a 350 with a 400 crank. A 350 bored 60 over is 361 cubes.
a Chevy 350 bored .060 over would be 360.4 cubic inches
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.
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.
First things first. You've defined the bore diameter (4.040"), but not the length of the stroke.
i have a 350 bored 40 over and 400 crank, and been told its a 383 stroker, what is it?

its called nothing because you wouldn't have a ENGINE left if you bored it 4" over

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.
