Grease and flour two 9x5x3-inch loaf pans.
Heat the oven to 350°.
Blend the eggs with the sugar and oil until smooth.
Combine the flour, baking soda, salt, cinnamon, and baking powder in a mixing bowl. Stir the egg mixture into the dry ingredients just until blended. Fold in the zucchini, pecans, and raisins, if using. Fill the prepared pans about half full.
Bake for 40 to 50 minutes, until a toothpick inserted in the center of the loaf comes out clean.
Makes 2 loaves.
