Carb for a street/strip stroked 440

[68-500]

Price of a new carb maybe halfway to a better mannered camshaft. Then you may not even need a new carb.
You can also adjust the accelerator pump cams and a different power valve might fix your fuel issues.

What exactly does “…the DP throws too much gas off idle” mean? Based on what you have, it’s more logical that your problem is being lean

If you cannot get the 4781 to work on what you have, it’s kinda hard to imagine you’re going to get an Eddy 800 to do better.
