Boy I'm not so sure I would agree with that. Of course the exact 4 barrel you compared with what 2 barrel makes a huge difference but guys seem to think that the front primary barrels of a 4 barrel are just like a 2 barrel. Not the case at all. This is why the SAE hg testing numbers for 2 barrels differ from 4 barrels. The signal to a 2 barrel is very different than the signal to the front of a 4 barrel. Runner configuration is also different on a 2 barrel intake and is designed to maximize fuel distribution for only 2 barrels. The 4 barrel intake does not do this. If we are talking ONLY fuel economy, I'd put my money on the 2 barrel for gas mileage and better throttle response.
