The Holley Strip Dominator manifold 300-25 has been designed for use on small block Chevrolet engines (262-400 c.i.d.) The 300-25 is to be used on 1957-86 all models and 1987 & later with aluminum heads. This is designed for competition and off-road use only. It has no provision for EGR and no exhaust heat to the manifold. This can adversely affect idle stability and part throttle operation, if used on a street-driven vehicle.
