A 350 starts out with a 4.000" bore and a 3.48" crankshaft stroke which really only gives you 349.8 cubic inches. (Chevy rounded it up to 350) Your engine which has the same stroke of 3.48 but now is bored .030" over (making the cylinder bored size now 4.030) total size of 355.1 cubic inches or just a 355.
Yes. That would be a 350 bored .030" oversize.
It ends up being about 361 ci
4.040". The standard bore is 4.00".
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.
In the mid 300 ish Hp
No a 383 is a 350 with a 400 crank. A 350 bored 60 over is 361 cubes.
