A Carter is in my opinion a tuners dream. Very well designed and unlimited adjustabilities, also a track parts kit will give you all the jets and metering rod combos you will need. On the down side all the adjustments let you screw it up big time if you just start changing things unlike the Semi controlable fuel leak (Holley) that is plug and play.
As to right for your engine that will take much more info. The list # on the choke horn or top left if a comp series will get you started on research. Web has some great places and will also tell if you have RARE carbs as well.
