The pump is mounted under the radiator on the right frame rail in front of the k-frame. I thought I read somewhere it flowed like 20 gpm. It is set up on a relay. The top inlet of the radiator is plumbed to the cap and then to the top passages on the block, and the bottom outlet of the radiator to the pump and then to the bottom passages on the block. I will try to get some images posted today..
