q: holley 650

  1. Hotrodding Basics
    First Time User Here But plenty of experience with Chevy, GMC... found a inexpensive Holley 650 Duel line, part number on carb [List 4777 0805]...What does this fit? I have a 1986 GMC 3500 (1 Ton) with a 350 (small block) needs a carb. Can I use an adapter to fit a 4777 to the manifold?
