Carb jetting
I've got an Edelbrock 1405 carb on my truck. I'm getting pretty dismal fuel economy even driving like a grandpa. My buddy thinks edel carbs are gas suckers to begin with, but I've never heard that before. Of the 600cfm performer carbs, the 1405 is supposedly jetted for performance and the 1406 is jetted for economy. Would I stand to gain any noticeable mileage improvement by changing the jets in my 1405 over to a 1406 set? Thanks!
