Hilborn small block Chevy injection manifold. Comes from the estate of a retired racer, been sitting in a Southern California garage for the last 20+ years. I know nothing about this system this is way beyond my area of expertise. If you have any questions please ask. This is being sold as-is. Very expensive to ship. I researched a lot of systems and have never seen one with the aluminum tanks on the top like this unit has. Any thank you.
