a Chevy 350 bored .060 over would be 360.4 cubic inches
355
No a 383 is a 350 with a 400 crank. A 350 bored 60 over is 361 cubes.
Chevy 350 engines are bored to a 4 inch bore.
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.
its called nothing because you wouldn't have a ENGINE left if you bored it 4" over
Most builders feel it shouldn't be bored over 4.065".
Its a 355 cubic inch

a 357 Chevy is a just a smallblock 350 Chevy bored .040 over for a total CID of 357, just as one bored .030 is a 355 Chevy. a standard rebuilt 350 is generally bored out during the rebuild process to usually 355, sometimes 357. right now i have a 357 Chevy in my 1970 chevelle
