Blue Thunder is widely known as the standard in Ford performance, and their Weber manifolds are no exception! This is the same weber manifold that Redline Weber uses on their premium 302 IDF applications and is also the manifold we use to replace inferior Weber kits coming from overseas. Blue Thunder manifolds have been used by most all the major Weber and fuel injection engine builders, including: Rough racing Engines, Holman Moody, Carroll Shelby, Redline Weber, Competition Cams, Inglese Induction etc....These ports come as cast for the original iron style Ford cylinder heads, however if you have aftermarket aluminum cylinder heads that have a larger intake port; please let us know as we have a version port matched (by Blue Thunder) to use the more common Fel-Pro 12625 intake gasket used on aluminum style heads.
