The bracket that goes on the top of the across the waterpump housing is the same for 400 or 440 , the one on the rear to the intake or the head is 400 or 440 specific because of the difference in deck height of the engine . Is there one on the intake on a big block? I've only ever seen one on the rear that connected to the drivers side most forward bolt hole just ahead of the intake manifold , sorry , no pictures .
