The carb on my 1969 Chrysler 300, 350 hp non TNT engine, has hit time for rebuilding. I thought it may be a good time to look into a brand new one.
What would the recommended carb for this be? The car is used for cruising and summer daily driving both highway and in town.
Speaking with Mancini, they recommended the Edelbrock 1406.
Anyone have any suggestions or is the 1406 the right one?
Thanks for your time.
Robert

The CarterBrocks are not bad carbs, but their basic design and calibrations are ancient. They really need to be updated. The go-to stock replacement carbs in my opinion are the much newer design and calibration of the Street demons, which are kind of an updated version of the ThermoQuads that replaced the CarterBrock design nearly 50 years ago. I truly believe that the only guys that still recommend the ancient CarterBrocks over the new Street Demons are those who have not tried an SD yet. And without that experience, just how valid is their opinion? Get the black center version of the 625. They also have a 750, and you could consider that one, but the 625 is probably enough for your application. https://www.youtube.com/watch?v=oVcUEHg30nAhttps://www.hotrod.com/articles/street-demon-750-carb-review/
Master, again and still

I use a lot of Edelbrock carbs and the 1406 is a great choice for your engine, I have used this carb on mildly warmed up 440's(mild cam,intake and headers) and it was very responsive in street driving. If you want to spend some more, the AVS works well also, but 600cfm is more than enough for your application. Thanks for confirmation of all that. I appreciate it! Did you require anything additional to install? It all fit? No spacers required?

I'm using a "modified" 1407 edelbrock on a 440. got tired of the factory avs's dirty burn and thought i'd try something different. used all the factory choke stuff and slipped in a primary shaft with a mopar throttle arm. works pretty good. burns much cleaner, drives nice but I think the factory avs makes a little more power. my next step is to see if I can find an edelbrock avs top for the 1407 to make secondary tuning a little easier. Interesting. Would be curious to hear how you make out!

Would be curious to hear how you make out! the 1407 works pretty good. been playing with it for awhile. it's a $40 swap meet carb I found, cleaned up, and swapped the parts out and it's on a stock intake. i'll see if I can get some pics. as for your stock avs they're very easy to rebuild; if you can find the right kit.

Thanks for those pics. They do look good!
Finally got into the car last night. Looking at my carb, it is a Holley 4166. I presume that is a 600?
