LOL this is why I don't post very much anymore LOL and why I told the Op in a PM that I would rather have phone call than discuss this on the forum.. while there's a lot of knowledge out here there's a lot of repeated miths and hearsays ..Ok wise ***, in a tunnel ram yes shared plenum. But some dual quad intakes are dual plane correct? I’m no expert, don’t claim to be either, just my understanding. On a side note i’m curious as to why on single four barrel tunnel rams, the carb is mounted in the middle? Better fuel distribution, aesthetics?
