That car didn't come with a 460 engine. They had the 289 ci, 390 ci and the 427 ci engine available in 1965. If it has the 427 ci engine it could be worth in a low retail situation $3,475. Average retail $10,300 and in a high retail situation $13,350. It's all about condition and factory options.
the answer is 357 ci (and some change).
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.
Normal Bore is 4.0, Stroke is 3.98. 30 over bore is 4.030. Radius of new bore is 2.015 Volume of 1 Cylinder is ((2.015*2.015)*3.14)*3.98 or 50.74 per Cylinder 6 Cylinders so new displacement is 304.45 CI
It ends up being about 361 ci
That would be an engine whose cylinders have been bored .030" oversize and fitted with new oversize pistons. New displacement would be 355 ci.
