Why not run a 4bbl? Those adapters frequently leak. Anyway, glad they haven't uttered the word CRACK!

i'll weld the adapter right to the intake, i'll buy a new 4 barrel carb when the new intakes are made, i think the 2 barrel will be a much better fit with those small intake runners and ports, i may have to plug one side and make it a 1 barrel. LOL!

You are aware that a 2150 flows about as much as the front half of an Eddy 1406? The big 2150 for our trucks was rated at 351 CFM. But that's rated at 3" of mercury, and 4bbls are rated at 1.5". To convert you divide the 2bbl rating by 1.414 and get 248 CFM.

Compare that to the 600 CFM Eddy 1406. But, the venturi diameters are different, with the front having 1 3/16" venturi and the rear having 1 9/16" venturi. Using the areas of the venturi to apportion the flow, the front would have 220 CFM and the rear 380 CFM.

Bottom line: The primaries on a 600 Eddy are smaller than the 2150.
