Carb Number help?
1973 F100 Custom 302 2brl 4x2 long bed
I am going to buy a new carb from advanced auto this week but i keep running into different ones other than what i have
First one : Advance Auto Parts: Carburetor - Remanufactured by United Carb - Part 7-7376A___#
I do believe that this is what i should put on there, seeing as how it is a motorcraft 2100 and all the threads ive read mention this as the carb of choice with the 2150 as an option?
The second one: Advance Auto Parts: Carburetor - Remanufactured by United Carb - Part 7-7581
i believe that this is a motorcraft 2150, and is what i have on my truck as of right now. I broke the climatic choke housing area and just dont really feel like spending 30 bucks on a crappy carb that needs replacing anyways.
What are the main differences from these spec wise? i know they look about the same, the 2150 is a little bigger than the 2100 but as far as "close to oem specs as possible" which one would you want to go on there and why?

We usually recommend to go to the Ford Motorcraft 2 barrel model 2150, which is (in our opinion) the best all around carb. We've ever seen. You don't lose much power or performance and you get a major leap in mileage.
The Ford Motorcraft 2150 is one of the last actual carburetors made before fuel injection, and in our opinion, one of the best downdraft carburetors ever installed on a 'factory' automobile. It's very basic simplicity yet very high efficiency ratio is astounding.
You can tell a 2150 from it's 2100 ancestor by the little rods that rise and fall in the venturis as you work the throttle. These small tapered rods make the air bleeds variable as the vehicle uses more or less fuel. This simple function makes the 2150 one of the most efficient carburetors ever manufactured. Because the Carburetor Enhancer actually enhances the operation of the air bleeds and because the 2150 has one of the best air bleed systems, we've doubled the mileage of these carburetors more than any other."
