street avenger advice

[lil red]

looking to purchase a 670 street avenger for the 360 and the original version and the newer aluminum are priced about the same up here at the local speed shop ( the newer aluminum is actually cheaper)

just wondering by fabo experience - are they basically the same performance wise - I realize the aluminum version has 4 corner idle mixture screws, so the original doesn't have this feature?

thanks fellas for any info or feedback about how it works ootb.
