360 .060 overbore too much ??????

I read somewhere that the best 360 to use was the 1971 blocks. The reason? The rumor was that the 71 year 360 was built using the 340 casting cores. This explains why 360 engines used the 340 style left engine mount.
340 engines had a standard bore size of 4.04 inches vs 4.0 for a 360. Assuming a .040 limit ( Yeah, sure!) If a 340 could be bored to 4.080, a 1971 360 should be able to be bored .080 over.
Of course, I would suggest a sonic check.
