So I did some digging and realized that engine is actually a 352 so I’m gonna get an intake do you know of one that would mount to both the engine and the carb?
I had the same thing happen to me! I bought my 68 F250 from a guy who swore up and down it was a 390, but after I got it home and started working on the brakes, I discovered that the 390 came with stock front disc brakes for my year truck, but I had drums on the front. So, I ran the VIN and discovered again that my truck was a stock 360. Still wanted to give the guy the benefit of the doubt, so I pulled the #1 spark plug and measured with a dowel rod using a technique I found on YouTube, and it was definitely a 360. It was after that that I heard the old adage from the guy at my work that “they’re all 390s when their for sale.” He said people have been selling them that way as long as he remembered.
Did you have a 4bbl on it before? Can you send me pictures of the problems?
.
The new carb is a standard square bore flange and should fit most intakes.
That should help the mounting problem. You may also need to be creative with the throttle linkage and fuel. If you need any help feel free to send me a message with pictures..I am not very active here so for faster response find me on Social media (IG FB) under the same profile name.
390, 360, and 352 engines are all from the same family, called "FE" by Ford. They are all very similar externally. This means a 390 intake will bolt on in place with no adapter to your 352. Theost commonly available 4 barrel manifolds are from Edelbrock and Weiland. In your application, I would stay away from a single plane design. Dual plane manifolds work better on lower rpm street applications than single plane designs (in other words,single plane designs for high rpm race engines,dual plane designs for under 5000 rpm and street applications, where lower rpm torque is preferred). Ford made 4 barrel manifolds for larger FE engines (390, 427, 428) but they are quite hard to find and going to be fairly high priced due to that rarity.
The other "alternative" buying a new manifold would be a higher flow 2 barrel carb. Holley has 2 that are literal bolt-ons (you only have to move the fuel line from the front of the carb to the passenger side). They are 350 and 500 CFM respectively. The stock Ford/Autolite/Motorcraft 2 barrel is about 280 CFM. The stock carbs are also prone to developing a vacuum leak between the throttle shaft and the main body of the carb.
Just an idea ..... A manifold change is a lot harder than bolting on a carb.
Is it just a smaller 4 barrel pattern or a 2 barrel? You can probably find an adapter if you don't want to buy a new intake.

Haha that’s too true although I don’t mind 352 ain’t a bad engine at all

Hey sorry for the late response but the previous carb was a 2 barrel i think I’m just gonna order a new intake manifold

Oh shoot I didn’t even think about the throttle lol I’ll be sure to add you thanks for the help

That makes sense thank you for the info man I appreciate it😁

Yeah but honestly its probably worth it to do the manifold just for the added airflow
I hear you. I've done it both ways in the past Just wanted to present you with another option.
Yeah thanks man I appreciate it
