Sidewinder Intake
The sidewinder intake is a great intake ... the offset is to give you all equal length runners . I have one on my 63 1/2 Galaxie 427 currently . I changed from a dual quad original intake to the Sidewinder and picked more bottom end end mid range with no sacrifice on the top end and I shift at 6200 rpm... and all plugs read equal , which was a major problem with the original manifold . I am replacing it with a Blue Thunder medium riser dual quad only because I want to use the Sidewinder on my big block Cobra engine as it has Cobra cast in the front . My engine builder says 600+ hp should be attainable with this intake . As far as fitting into an ERA ... I am getting an ERA and in talking to Doug at ERA , he said this manifold will work fine and has no clearance issues as the engine is offset a little anyway and this will move the carb almost back to the center .... but you might check with him anyway .
