Its spelled nozzle, the first thing is make sure their is no clearance on the pump arm at idle and .015 when full open. Then play with cams so you have the big hit initially and then taper off and or put them in the #2 slot and finally get a holley book that has the different pump cam #s and how many ccs of shot they produce and when. Going up in size isnt always better as it needs to be tailored to the combo. The pressure thru the nozzle will be less as the hole gets bigger,and if you are wide open,it isnt in the picture anyhow.
