What would you choose between a 5.4 2V and a 4.6 4V? Lets say they're both equal in terms of boost, compression, modifications, etc...which one would you prefer to have, which one do you think is superior, and why?
You can't beat the sound of a 4.6 4V. If money isn't an issue you can build an 8K RPM screamer, or when boosted the 4V heads flow so well it's easy to cram lots of air into the combustion chamber.
5.4's are alright, but there aren't really any good intakes available (unless you are using a lightning supercharger), the bore diameter is very small while the stroke is very long (not ideal), the 5.4 is heavier than a 4.6, etc...
4v is superior to the 2v, but the 2v is still a great motor and has lots of potential. Blown, built 2v can see 600+ hp which is more than enough for most.
