I am about to send off the carbs for my Six Pack Superbird (auto) and noticed the center carb number is 4144. The front and rear numbers are 4382 and 4383. My books say the 4144 carb is for emission cars which this car is not. Could this carb be right? Date codes are good. Car is supposed to be all original. Any ideas?
