Surging

Ok the carb I bought it from rock auto about three years ago and maybe drivin the car maybe 300 miles and it's always had that problem and people are telling me I'm starving the 360 you need to go to a 4 barrel and I'm like hmmmmm but your telling me it could be a dirty carb or timing I'd rather try your idea and yea it's more like bucking when your driving it
