I need a carburetor for a 1986 F-250. I do not know the size of the engine and was told I needed to know that to get the correct carburetor. How do I find the engine size? Also, the carburetor numbers I currently have is
E5HE-9510 LC
LIST-50263-2
2526 H4852
Any help would be appreciated.

 

There should be a sticker on the radiator support that says 4.9 or 5.0 or 5.8, or 7.5.

I guess you know if you have a six cylinder or a v8? If it's a six, then it would be a 4.9.

If it's a v8, then it could be a 5.0, 5.8 or 7.5. A 7.5 is a 460 big block, and the only thing I can say to describe it is it's huge.

If your engine is smaller, it could be a 5.0(302) or a 5.8(351w). It should have six bolts holding the valve covers on, and here's a trick to tell the difference between a 5.0 and a 5.8.

 

Thankk you, now where does one find a carburetor for this enging? I have looked on Holley's website and several other places and cannot find a 50263 part number anywhere. Any suggestionis?
