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

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.
It's a .060" over 350 with a 400 crank
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.
