as for the engine thats kinda your choice. the 429's are interanlly ballenced and rev a bit higher. the 460's before `72 had 11:1 compression and ran premium fuel. the later 460's had open chamber heads so they run regular. and last I knew ALL 460's are externally balenced
. they did change deck heights on blocks around `78 or so. about the only thing in your favor at this point is the bellhousing pattern is correct.
