I have a 427 with a Eldabrock Torqer 2 intake in my car. The manifold is very short and a single plane design. I am considering adding a 1" spacer in order to get more clearence to allow room to do something different with the double feed fuel setup on the Holley. I think an easy, cheap, clean way to do it is with one of those chrome doublelines, but the intake is too short to point the line towards the front. So the question is, do I try an open spacer or a four hole. This motor rarely sees over 5000 RPM. Can any one comment on that?
