Dual Weber 48 IDA carburetor kit with standard manifolds. Comes with competition cross-bar linkage in the hex aluminum style. The kits is supplied with both the aluminum crossbar mounts at the velocity stacks and steel mounts which allow for for air cleaner use. Standard intake manifolds are clearanced for the area around the upper intake port at head and sheetmetal to limit modifications for installation, but still allowing for match porting with no additional welding required. Manifold has the same basic “stock” port design at the base of the manifold so they can be precisely match ported to your particular port shape. Kit does not include air cleaners.
