[Cobra #3170]

I am going to be in the minority here because I care about function more than appearance but here goes. When I first got my Cobra it had a blueprinted medium riser with dual fours and vacuum secondary. I never had any trouble with that set up other than flooding during anything beyond a mild cornering maneuver. I had the stock Stellings air cleaners that proved inadequate until I increased their height with taller elements. I have run dual center pivot two barrels on a dual four tunnel port single plane manifold with good power and drivability but the best power was obtained with a single blue printed 1150 Dominator on a single plane tunnel port manifold with a 1" spacer and NASCAR air cleaner. I know most of you like the looks of a turkey pan but the little air cleaner that most use with the turkey pan will not flow enough air for a 260" small block.
You will have less trouble with a single four but the dual four looks better and works pretty well for everything. Weber's or Stacks also look good but are hard to filter, produce tons of torque which you don't need, and are a nightmare to tune properly.

Unless you are good with carbs I would go the single four route with a BIG air cleaner, you can put the turkey pan on for shows.
