I have a holley 650 dp that has no vacuum ports. I drilled a 1 inch spacer and press fit the ports that I need. It works great, except now I can only run a 2.5 inch airfilter cartrige on a drop aircleaner. I think the top of the aircleaner should be higher than it is. Has anyone drilled and tapped holes into a dual plane rpm? I need a port for my dist. one for brakes, and one for pcv. Would I drill them on the short runner side or the long runner side, or should I drill them right at the divider?? Thanks for your thoughts.
