Carter AVS questions

Sorry about the hijack ,just curious, is your car an automatic and is that the original carb? My 69 340 has the original carb A9 4611SA and is a 4 speed. I had a discussion with someone who has a 4611S and he said that was the 4 speed carb. Not sure what the A stands for.
No problem. Yes, it's an automatic and it is the original carb. At least I've had the car since 85 and I'm the 3rd owner and know the history of the car back to the first owner.
