what is the number on it ? AVS was used 69 , 70 , 71 , there is no vent tube so it's not a 71 cab , or a 69/70 with ECS ...




John, you forgot 68 AND the AVS was actually used as early as 66 on the 275hp 327 Chev. I once found that setup (intake and carb) for a friend for $10....





And did you know the AFB 3861S was also used on the 409 Chevy 2x4"s ?




Nope, didn't know that, but I've probably got some




Really not sure how that happened. I don't have the carb, but I do know that I've got info on the carb in my shop manuals...
