I need to know the application. I called Edelbrock and they didn't have anything in their archives on 'em. Google also comes up empty. So, they're Edelbrock M17-3. I thought port size and spacing might help: the ports measure approximately 1-7/8" square, and the measurement between the 2 outside walls of the outside ports is a hair over 16". There is 3" between adjacent port walls. Any ideas? Gen 1 or 2 HEMI? Last edited by vdriver; 04/05/17 04:39 PM.
