What are the smallest jets that will fit a 600 CFM edelbrock carb?

What are the smallest jets that will fit a 600 CFM edelbrock carb? i want to know so i can get a little better gas mileage|||USE EXTREME CAUTION WHEN MAKING JETTING CHANGES ESPECIALLY WHEN GOING TO SMALLER SIZE!! If you are not an experienced mechanic with specific knowledge of carbs and tuning fuel mixture through jetting I recomend you not attempt this. Reducing jet size leans the fuel mixture. As the mixture gets leaner the combustion temperature increases. Excessively lean mixture will result in engine damage, from melted or cracked pistons to warped or distorted valves.


All that aside, are you aware that edelbrock just chromes and renames a Carter AFB? This is one of the best and most reliable carbs made.


Wide open throttle fuel mixture is determined by “reading” the spark plugs after a 10 or 15 second run at full throttle. Black soot is too rich, reduce jet size. White insulator is too lean, increase jet size.


It's a rather involved procedure and will only slightly increase fuel economy.
