What are they?
« on: June 20, 2010, 03:30:53 PM »

What are these two carbs, and which is the better one to use on a relatively stock 413?
 
This one is currently on the 65 413 I am going to put into my 300.
 

 
 
This one is on the 67 440 that is currently jury-rigged into the 300.

Carter AFB's.  One has an internal choke pull off.  Other than that they are both pretty much the same

On the second one, what's the number on the tag on the front screw by the vacuum pod? Does the first one have a tag on it anywhere?

The top one should too.  Maybe it's missing

Sometimes the earlier ones have smaller carb plate bores.  So I would check the 67 vs the 65 and choose the one with bigger bores.  But then also check the intake youplan on using, since they too can have big and small bores. 

You don't want to end up with a bigger bore carb sitting on a small bore intake....your throttle plates will get jammed wide open and then the fun begins....

Looks like the 413 has the original 3858S. It is on a manifold I can't read the whole number on. The first 3 digits are under the carb. It is xxx6000 - also has  these on it  HW  and  N1.
 
The number on the carb base  on the 440 is 4312S and has the number 66 below it . The manifold on that one is 2806178.
 
Which would be the best combination? and what are the carb sizes?

The one on the bottom is at least a 1969 carb, based on the first year the little air vent on the driver's side (rubber plug with the wire to pull it open when you push the gas pedal). They work to prevent vapor lock in the bowl when hot, allowing ambient air to reach the fuel bowl instead of gas bubbling and pressurizing inside.

I thought it was 68 as the first year for that vent cap on the float bowl?  My numbers carb I had on my 68 383/4bbl had that.
