The "little bird" I'm less familiar with, but those were an earlier engine family: the Y block.
The 390 FE started out as a 352 in 1958. The 427 had a very large bore and was expensive to manufacture, so the reduced the bore and lengthened the stroke for the 428. The 390 is the most common of the family.
The 429 was made from the bigger big block 385 series engines. The 460 is in this series.
