Does anyone know where I can purchase a 4bbl intake manifold for my 66 barracuda 273 with a 2bbl. I want upgrade to a 4bbl carburetor but want to get the right set up.
Any 273 or 318 4 barrel intake will work on your 66 273. I usually run a 500 cfm or 600 cfm AFB or Edelbrock copy. You will also need a 340 throttle cable mount and , if Automatic transmission, kick down linkage or kick down cable kit. Make sure your carb fully opens when the throttle is floored.
