Like there are FAQ sections, there should be FGA sections or Icons or acronyms too:

1) What is your budget?
2) What is your intended use?
3) What is your involvement in the build and ongoing maintenance of this engine going to be?

1)The Windsor would be cheaper.
2)Either engine can weigh the same (with substitution of aluminum parts for iron on the FE), so each could handle the same, and they both displace 427 cu inches. UNLESS, you plan on going for more displacement at some future time, then 427 is pretty much max on the Windsor.
3) You will find more people and shops that are familiar with the Windsor as far as repairs and parts go.
