Smallblock intake manifold shootout.

I wonder why I've never seen any magazine run a intake comparison/shootout that includes any of the Offy manifolds. Some people love them and some people think they are junk. I've never seen side by side comparisons between them and the other brands. The old Direct Connection engine book said that the Port-O-Sonic (with mods) was the best intake for a bracket racing combo, but you never see it mentioned at all these days.
