That would be an engine whose cylinders have been bored .030" oversize and fitted with new oversize pistons. New displacement would be 355 ci.
Bore it .030 over. A 350 has a 4 inch bore. When you go .030 over, the cid., becomes 355.
Yes. That would be a 350 bored .030" oversize.
4.030"
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.
350 block, 400 crank. Main journals must be turned to accept 350 bearings. Stock bore is 377. .030 over is 383.
A 289 bored .030 over.
332
It will be close to 315 ci.keep in mind that a 350 is not really 350 but 349.xx or look at this way, for every 030 over in bore = 5 ci.
.030"
A 262 bored 30 over.
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.
A 383 is a .030" over bored 350 small block with a 400 crankshaft. The 454 is a big block.
