They took one of the 82-84 Crossfire injection intake manifolds, made a cover to mount dual 4 barrels on it, and are trying to pass it off as cross ram manifold. I hope someone unknowing doesn't end up buying that because they will be very disappointed. If it wasn't for those extremely small ports, that might actually work.
