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
10 degrees with a stock cam
A 348 Chevy engine has a stock displacement of 348 cubic inches. When the engine is bored .060 inches over, the displacement increases due to the larger cylinder volume. This increase is approximately 5.1 cubic inches, bringing the total displacement to about 353.1 cubic inches. Therefore, a 348 Chevy bored .060 over is approximately 353.1 cubic inches.

The bore adds about 10 cu. inches to make it a 337
Sounds like a 343 to me. But for parts its a 283 bored 60 over
If my math is correct , just over 362 cubic inches ( 4 inch bore x 3.5 inch stroke , bored .060 inches )

a BOSS 414!
any Chevy 305 block can be safely bored .060 over. if you have a good block, with thicker cylinder walls, it might be .080 borable.
If my math is correct : using a 4 inch bore and a 3.48 inch stroke , with the cylinders bored .060 , just over ( 360 cubic inches )
