This is a 3-2's I did on a 57 Ranchero motor , just used the kit 4-bbl intake and carefully filed down the sides of the carb mounting base till the 3-2's fit right then simply glued the tri-power set up in place .
Some nice work on this looking very nice . The AMT 1966 Fairlane GT/GTA kit has a nice FE motor and a C-6 , if you can't find any PM me I might have a extra one but can only be built stock .
