AJ...I hope I have the right person...I have a 750 holley carb I want to but on a turbo draw through turbo setup.. How do I vacumn index it so it works.. I hear that you have overcome this problem.. I have heard that I need a different power valve or something...where could I pick up an non turbocharged vacumn so that this thing works.. Plan on putting this setup on a Holley 4 barrel Dominator manifold..
