I think your picture with the 4375 list number is wrong,the 4375 is not a dual inlet center hung float unless someone changed the bowls.
‘71 carb?

what I have found is
the main difference besides the list numbers on these carbs is in the metering block
some of the vents off it will be different
and also the idle circuits could be different per application.
the 6193 I got had the wrong metering block in it , the vent was wrong
(common because these carbs seem to gum up fast and run like crap
and they were also known to be leaky so they tended to be monkeyed with over time)
when I started to dig further
there are a lot of different metering block part numbers that can go with these carbs.
and some of the blocks even interchange with....Chevrolets!
don't forget Mopar wasn't Holleys only customer
so I'm sure you could make it work with some research
the guy who posted above me ^^^ is the man you need to talk to!..lol
I happened to find a correct nos metering block for my carb
thanks to the help I got from Bill O

What if anything goes on the driver's side of the carb? You can see in my first picture there is a spring loaded screw that goes to nothing on my carb???
Thanks Ron

So at what point where a lot of these factory Holleys replaced at dealerships with the Carter AVS 6125s
1971 383 HP
I thought I read somewhere about a Chrysler bulletin or something related with the Holleys and dealerships where installing Carter AVS 6125s conversion kits on the 1971 383 HP

There may be a TSB associated with replacing a Holley with a 6125 Carter AVS but I haven't seen it (or don't remember it). Either way, the Holley 4 barrel line for the 1970 & 71 383 Chrysler applications were known to be a problematic design (they can work well but a lot of people have issues with them even today). Carters are a much simpler and easy to keep in tune, especially by novice owners. That said, production line correct is what most people care about when doing a 100% restoration on a car so replacement carbs, even if suggested by a TSB, don't care much weight when discussing correctness or originality. .02

While it’s been many years, I’ve seen this document and referred to it many times to perform this conversion while working at dealerships in the mid-seventies. It was a complete factory prepared kit that included hard fuel lines, divorced choke, and all necessary hardware for a factory appearing installation.
Problematic? That may be an understatement, the OE Holley’s of that time had a terrible reputation for leaking, warping, cork gasket shrinkage and generally undependable. Many engine fires were attributed to them.

I'm pretty sure my '71 Charger/SuperBee came new with a Carter AVS, 650cfm if I'm not mistaken; I'm now using a Holly 750cfm dbl pumper.
