4-barrel manifold comparisons/choices

[Ricardito]

I'm considering the purchase of The Z Store 4 barrel manifold (Clifford) and The Arizona Z Car manifold to install in my 280Z engine instead of the factory FI set up. Both manifolds are designed to work with a Holley 4-barrel small 390 CFM carburetor. I would appreciate very much the opinion of those of you here who have experience with either of these set ups. My purpose is to simplify and make my car a more reliable everyday driver. Additionally if anyone here has one for sale I'd be interested in its purchase. Please email me directly at <landeira@colorado.edu>. Any and all advice is much appreciated.
