I'm wondering the same thing. Is it true that on the street hemi 2x4 dual plane, the 2 front & back longer runners required staggered jetting to avoid a lean conditon in their cylinders? How would that be affected by a single 2 bbl carb over the center runners? If the air/fuel mixture has more time & room to atomize in a dual plane, would larger cfm 2bbls be required? Finally, would the short runner, single plane 2x3 intake run better w/ smaller carbs? Finally, would mechanical linkage be best suited for the hemi w/ the 3x2 setup?



Don't know about the in-line, although they are staggered oon my x-ram. My guess is that like the GTO tri-power, the outside carbs are larger than the center one which negates the requirement for smaller carbs as the car is normally running on a
relativly larger center carb. Mechanical linkage? Well, I guess you could, but like the Pontiac set-up, I believe they were vacum from the factory but alot of guys changed them over to mechanical once they got them.
