the two things that are different from a 429 and 460 is the crank and pistons. the rods, heads, valvetrain, block, etc are identical and interchangeable between the two.
the 429 piston has a different pin location than the 460 psiton due to the longer stroke of the 460. so to make a 429 into a 460 you have to replace the crank and pistons. pretty simple way to get an extra 31 cu in.

You need to make sure you have a 429 flywheel or flexplate as the later 460s (1972 on on) were externally balanced and the 429 were not.
