It is mostly visual. An FE looks pretty awesome with 2x4s and S&H air filters. I've run them on 2 FEs now, and they work very well - assuming you get the correct linkage and carburetors.

The only hassle I have right now is a tendency to die when making hard left turns. The side hung floats are much more sensitive to the fuel level in the bowls. It is fixable, but on center hung floats it is a non-issue.

I would probably run a single 4 on a 351W, though. 2 Holleys on a 351W looks top heavy.
