350 small block

  1. 350 small block

    I have a 1988 chevrolet 3500 with a 1978 350 small block in it with a 4 core big block radiator in it and am using a flex fan right now but it's running really hot in town. And when I took the water hose off only a gallon of water leaked out n it was completely full the other day
