I'm selling an Edelbrock EDL-5421, C-66-R, dual plane, dual carb, rectangular port, square bore manifold.  I bought it from Summit Racing on 10/16/08 for $322.  It was installed mid-09 and used for roughly 25 hours.  I'd like $100.  You can leave a message for me at (818)998-seven four five seven.  Email mafman@sbcglobal.net    Mark
