340 A body versus 383 B body

One of the tricks was to replace the 340 carb with an AVS off a 440. Most people wouldn't know the difference looking at it.
Most people didn't know how to set them up. lol
The old man and uncle did though.
I sold all my Carters and strip kits after trying a 750 DP my friend lent me, a far better carburetor. imo
