6 out of the top 7 motors in the engine masters series were CHI Cleveland head windsor blocks. Windsor heads can never out flow Cleveland heads! Compare apples to apples here. Either stock vs. stock or aftermarket vs. aftermarket. Just like the FE, Clevelands are finally getting the attention they deserved. The only advantage the windsor block has is that it is taller and can be stroked more. That is why the Clevor is the popular choice of the engine masters competitors. If you are going with stock heads go with the 4V Clevelands, in a cobra, in this lightweight car there is plenty of torque off the line and once you get above 3500rpms hold on!
