well to answer my own question since nobody else has....I just called Clifford Performance and they told me that their 4bbl intake doesn't fit with Fentons...don't know if they're just trying to sell me their headers or not?

Also they said the best carbs to use are at least 390cfm 2bbls. They said the Webber 38 is the best choice and that staged 2bbls are too small.

I'd like to get the opinion of someone other than someone who's trying to sell me something though.
