i think this is their action plus manifold. it is the only dual plane that i see in summit. it is for a sbc and is in great shape. all the hole and mounting places are in great shape. the threads are not torn up in any way. the only thing visible is that it is dirty. has been on my car for 3 years now and could use a real good bath. made great power jsut decided to go with a polished manifold. 45 obo email me at
