For all around drivability, power and economy, the EFI wins. Its not terribly difficult to set up a carb to beat EFI at one of those, but at the expense of the other two. You can delete the smog pump and all its associated plumbing without hurting anything. Don't delete the the EGR unless you plan on reprogramming the computer. It doesn't hurt performance and will trip the CIL if its gone. If you really want the EFI gone, go all the way and drop in a 351W. Gobs more power and torque and it'll bolt up to your existing transmission.</blockquote>
