440 Build Suggestions

Either upgrade the valve springs and rockers or go with a .501 lift cam ( still need better springs). The .545 cam doesn't start to work below 3500rpm . With your gears the motor will feel lazy going down the road . 575 h.p. sounds a little ambitious to me . If you want 575 , you need a looser converter and taller gears . You won't like it on the street , otherwise .
