super six intake and 318 carb

well damn ,it's running.so heres your answer...yes it has a noticable power gain.but,the idle is just a little too high.the idle adjustment screw is all the way out not touching the stop.needs to be 100 rpm slower.i adjusted the mixture screws with vac gauge.the engine runs much smoother with the two barrel.sounds better too.the carb came off a 318 itsa carter.it has a hole in each butterfly like you would drill in a holley so it will get more air at idle with a big cam.think it will idle down if i plug those holes?
