On many automotive motors the water pump is mounted at the front of the engine and ported to passages in the block. In a marine motor conversion the automobile water pump is eliminated, leaving open ports that must be blocked off. Our water cover plates are made from highly polished cast aluminum. Sold by the pair.
Note: All water cover plates are tapped for 1/2" I.P.S. pipe fittings.
For Chevrolet 265, 283, 327, 350, & 400 Cu. In.
