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 )

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.
No a 383 is a 350 with a 400 crank. A 350 bored 60 over is 361 cubes.
I've heard of going .060" over, but most builders feel .030" over is the limit.
Depending on the piston type you are running, you would bore .030, .060, .090. Or, .020, .040. At .030, you come out to 355. So, at .060, 360.
A 383 Chevy is a 350 block with a 400 crank bored .030 over. If it's not bored oversize it's a 377 (Not the only way to make a 377). If it's .060 over, it's a 388. Most builders agree that you cannot safely bore a 350 block .090 over, but if you did the resulting engine would be about 394.
