Preheat oven to 325 degrees F ( 165 degrees C). Grease and flour two 8×4 inch loaf pans.
In a large bowl, beat eggs until light and frothy. Mix in oil and sugar. Stir in zucchini and vanilla. Combine flour, cinnamon, soda, baking powder, salt and nuts; stir into the egg mixture. Divide batter into prepared pans.
Bake for 60 to 70 minutes, or until done.
