I had just finished rebuilding a 440 Magnum for my 69 charger RT to stock specs and I am now to the point of adding a carburetor. What CFM Carter Carb came on the 440 from Chrysler? I would just like everything to be matched. Also I was thinking of using an edelbrock carb in place of the Carter since they are similar and the edelbrock is more common would that be a good idea?

The 1969 HP440s used,

Carter AVS 4617S............w/ 4-spd
Carter AVS 4618S............w/ Automaic
Carter AVS 4640S............w/ air conditioning

They all should have been 750 cfm.

You can use the Edelbrock carburetors if you wish.

There's a cool formula you can use if ya like to get into the ballpark.

CID x expected RPM / 3456

When I plug 440 x 5,000 RPM then divide by 3456, I get 636--so a 650 would do well.  RPM may vary.  Laugh

Why would anyone recommend a small block size carb for a thirsty 440. A properly tunned stock running 440 will shift at 5500 RPM at full throttle all day.
If your looking for economy go with the edelbrock 1411, its a 750cfm set up for street use. If you want a little more go with the edelbrock 1413, it is set up for street/strip us.

Eh, was just an example.  I actually run the 1411 on my 440.  Smile
