Aussiespeed Chrysler Valiant Slant 6 AS0570 intake manifold. The latest in the line up is the AS0570. The new Aussiespeed slant six manifold is a 2 barrel short runner manifold that will accept 2 barrel down draft weber carburettors as well as 350 500 Holley 2 barrel carbs and throttle body fuel injection. The manifold offers the same performance as the AS0199/AS0214 Aussiespeed 2 piece manifold with some restyling to the out side. The manifold is 30cm or just under 12 inches from the cylinder head face to the widest outer edge of the carby pad. The Aussiespeed AS0570 has a textured grid cast into the plenum floor that can help with fuel re introduction in cases of fuel drop out due to over fueling, cold operating temperatures, or a fast drop in air speed due to deceleration.
