Don't mean to seem ignorant, but what is the difference between the AFB and the AVS?




Well assuming you are trying identify one or the other and not every single detail of what set's them appart?

These are AFB's (Aluminum Four Barrel)

There were two basic designs on Mopars, early and late. These are the early styles (with vestigial choke tube in the lid) found on early to mid 60's Mopars.
