Old CarKook,
You could probably answer this for me. Do you know the correct downdraft carb. numbers for a 54 GMC with the 248 engine? I actually have (3) carbs for that truck. The one that was on it was a Zenith 11275D, on there now. Next I bought was a Zenith 11280XB, and the third was 10569A it's the worst of the bunch. Have anyway of knowing if these are even the right carb for that truck?
Thanks
