best size 2bbl carb or small 4 bbl for my 318?
you can either go to a thermo quad or a holly spread bore as said,, or if your running a 318 mildly built a 500 cfm edelbrock will be plenty,,,and if you keep your foot out of it you will see mileage gains,,,,your factory 2 barrell is not more then 350 cfm,,unless its a big holly 2 barrell economy master they are 500 cfm,,,
i run a 500 edle brock on a 241 ci dodge hemi in my street rod,1940 dodge wit hthe A/C on and cruising at 75 mph i got 18 mpg with 3;23 gears and a 904 with a lock up converter,,
