"The truth is Pontiac engineers made such a good intake that the aftermarket has nowhere to pick up performance over it in a 2 plane intake. That's why the single planes can pickup performance over a 2 plane when it comes to more than a street engine, say above 500 HP. The factory dual planes are already very good as designed." Sirrotica Quote.

I have often wondered how frustrating it must have been for Edelbrock to spend time and financial resources to produce an aluminum intake manifold for Pontiac engines that was just a lightweight turd? They tried more than once too. The production iron intake and Q-jet carb that Pontiac made millions of was still the best performing set-up for engines up to 450-500 HP. That demands a whole different level of respect for Pontiac engineers vs say the "mighty Chevy" engines. Bolt virtually any aftermarket part including intake manifolds on a Chevy engine and it improves it! What does that say about the engineering that went into the original components? To me it says allot more about how good and well engineered the Pontiac engine was and a little less about how bad Edelbrock stuff was. JMO
