Hot Rod mag did a comparison test about a year or so ago using an FI LS1. They swapped on the Edelbrock LS1 4-barrel manifold/carb and made more peak HP in every test. The torque curve was a lot peakier however. Of course the EFI system is infintely more tunable, so there's that... The results really surprised me, I thought the FI would be more efficient by design?
