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?
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 ..
What about the cross ram?...
Every time I see a single four-barrel tunnel ram I think to myself WHY!!??... And if the four barrel was pushed to the front or the back I'd completely lose my mind... I would be under bad aesthetics overload... LOL..
Isolating one side of the other is not the same as isolating front to back. The carburetor will still run the entire engine just one side from the other not nothing going to the front if the carburetor is not on the back and a plate was placed over the top front carburetor which no one will do... You're still getting some air and fuel from the idle circuit of the front carburetor let alone when it's really pulling and opening up the back and secondaries...
Anyways I think I'm done here trying to mythbust...
If anybody's interested in my 10 plus years of tunneland experienced I'll talk to you on the phone..
