Yes. That would be a 350 bored .030" oversize.

The so-called 355 was simply a 'bored out' 350, so it could be made any year that 350's were available.

YES, A 355 is just a 350 bored 0.030 over very little difference.
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.
That would be an engine whose cylinders have been bored .030" oversize and fitted with new oversize pistons. New displacement would be 355 ci.
It is now a 355 CID.
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 a 355 cubic inch
have the cylinders bored .030" oversize and fit it with new pistons.
355 is a non stroked just bored 4.030 over 383 on the other hand put a 3.75 stroker crank and bored honed so i would pick 383 . 355 is bored not stroked clearence for stroker crankbest engine would say is 383
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
