a bored out 350 blockThat answer is right, but it did not answer your question completely.A 355 is a 350 block that has been bored .030 / thousand oversize from factory stock bore. Nothing special.

Bore it .030 over. A 350 has a 4 inch bore. When you go .030 over, the cid., becomes 355.

The so-called 355 was simply a 'bored out' 350, so it could be made any year that 350's were available.
Its a 355 cubic inch
have the cylinders bored .030" oversize and fit it with new pistons.
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

YES, A 355 is just a 350 bored 0.030 over very little difference.
A 355 is just a 350 bored 0.030 over. There really is no difference. this is true but to further the answer if only you bore the cylenders out in the block you will need to buy aftermarket pistons to make up for the new wider space so you dont have compkications with the pistons slapping the cylender walls
