Jerry I Have Done A Pile Of Digging For Answers And Keep Getting One Common Factor,this Main Body Is ,well,less Than An Engine Builders Friend.i Think Its Time To Put The Holley Back Together,the Proform Body Back In The Box And Take A Ride To Summit.since The Whole Point Of This Swap Was To Increase Airflow By Reducing Turbulence And Maybe A Little Better Fuel Flow With The New Metering,with The Engine Build I Have,what Carb Would You Run? A Demon? Edelbrock? Quick Fuel? What Cfm And Should I Run A Vac Secondary Or Double Pumper? Thanks
