I have a FORD 1977 2.3 OHC, 4 Cylinders engine. It is the same PINTO engine. It is the heart of my Jeep Ford, a CJ-6 made in Brasil by Ford. Manual transmission. Not computer or electronics. Plain old style, 4 spark-plugs, distributor with points and capacitor, coil. This is a street car, not racing. I need help finding the right carburetor for this engine. Please what brand, model, part #, cfm,  is the matching carburetor for this engine?.

Thanks for your help. Looking online I found 2 items: 1st item: Cylinders L 4 -  Liter: 5.7 - Engine Size: 122 - Manufacturer: Holley - UREMCO Part #: 7-7396 - Product Notes: Carb 5200.  2nd. item: Cylinders: L 4 - Liter: 5.7 - Engine Size: 140 - Manufacturer: Holley - UREMCO Part #: 7-7399 - Product Notes: Carb 5200.  I noticed the only difference is in the engine size. I am not sure if mine is 122 or 140, how could I get this? 

After taking a look at a lot of pictures online yours is a 2.3 Ford Pinto motor so use the 7-7396. Where are you located, I have some rebuilt carbs just setting in my storage unit. They are set up for a 1976 Ford Pinto with a manual transmission and have the electrical choke. The only thing needed is the  idle solenoid. Mine did not work.

Not so much knowledge , basically any 5200 Holley/Weber carburetor should work as long as it's not worn out or has allot of varnish due to our gas having alcohol added to it. I will take a look at my engine and count how many cam towers I have and you can use that info to ID your engine. I do not want to make a W.A.G. (wild butt guess). If anyone else has a picture of a 2.0 and 2.3 head with out the valve cover post it, it's hard to tell on the out of U.S.A. engines what he has. For example the timing cover looks a little different from what I have on my 2.3 but the engine as far as I can see is a 2.3.   

Your spot on in regards to the cam towers. 3 towers = 2.0.... 4 towers =2.3
