ycnan 18 Report post Posted February 25, 2015 '69 Mach1 351w. I am looking for a low to mid rise dual quad manifold. I have an Edelbrach Performer semi high (or semi low) with a 4v on it now and, with the air cleaner, it barely fits under the hood. The Edelbrach Performer dual quad durashine is nice but adds 2-4 inches to the height even with a shorter air cleaner. I really don't want to cut a hole in the hood. Does anyone know of another brand that will work for my car? 8 Ernestgaig, Miltonlob, Barrerakes and 5 others reacted to this Quote Share this post Link to post Share on other sites
69RavenConv 286 Report post Posted February 26, 2015 Blue Thunder makes a reproduction of the early 60's Cobra manifolds. I found this article on-line that discusses it and some other of the dual-quad options. http://www.mustangandfords.com/how-to/engine/mdmp-1207-dual-quads-twin-win-or-double-trouble-part-2/ Quote Share this post Link to post Share on other sites
