OK, I have a 1969 Roadrunner. It has a matching 383ci engine with a 4bbl carb. At the moment the car has an Edelbrock Carb, not sure which one but my guess is its the AVS version since that is what I understand was stock, the difference being Plymouth was using the Carter Carburetor. I believe from what research I've done the correct Automatic Trans and No Air carburetor was Carter 4616S. If you had Air and Automatic it was a 46385S. Not sure if they are interchangeable or not, but I would think the Air Conditioning Carb would work in a non-air car and not the other way around. To be honest, I'm pretty far from being a mechanic. I know where the key goes and where to put the gas in, but that is about as qualified as I am to work on an engine. Anyway, I've given some thought to finding a Carter and having it installed in the interest of originality. But I haven't read a whole lot of good things about the Carter, which I'm thinking is probably why the previous owner of the car swapped it out. Any thoughts on this?

 

Years ago like 30, I had a 68 Chry SW 440 with a factory Holley 4bb, carb Was in bad shape... Thru it in the trash and installed an AVS carb & the car ran like a watch. Also used mopar 9636 specific aftermarket Carter AFB on a 360 Volare hot rod I had with good results. So there a lot of variables, I would think most of the apps are just different linkages

 

Stay with the Edelbrock. You'll kick yourself for putting a carter on there unless it's a show car and you just want it to be original and you don't drive it on the street.

 

I agree. if your going to drive it, stay with an aftermarket carb..... now that being said from my cars and being at the track around a lot of big block cars I have not seen a lot of success with Edelbrock carbs on Big Blocks. From my understanding they tend to run on the lean side and mopar big blocks generally tend to like more carb. Just my experience but I have had much better luck with a holley or Proform on my cars.
