I know this is a little late for your swap meet but for next time heres the mother lode of Chevy, Ford and Mopar engine info and holly carb info. Go to ( http://www.speedfreaksspeedshop.com ). At home page, left side, click on #2 - tech info. and there youll find all that you need. When I go to swap meets, I always have a copy with me. Hope this helps. drm184
