You might see a few hp, but not much. The edelbrock tbi manifold also comes with egr and is basically a direct bolt on as compared to a carb manifold.

Just go with the Edelbrock TBI manifold I think #3704 and block off the egr as long as you don't want it and its disabled in your chip.

yeap, and 10 hp sounds about right. It won't be much, but every bit helps.

cant tell ya what the TBI intake does, but the performer carb with adapter is alright, feels like I lost a little low end, but all in all its good, love not having the egr croud the intake up, and the adapter makes it look like a highrise. Im still working out timing issues so that maybe another reason, do a carb intake save some $$$ its really easy the 2104 is a DIRECT bolt up everything goes where it came from...

I think NJ Speeder uses it in his setup and said the difference was noticeable.

You may be able to score a used one for a better price than new
