Preheat oven to 350°F (175°C). Grease and flour a loaf pan.

In a large bowl, beat eggs, sugar, oil, and vanilla together until thick and well combined.

Gently fold in the grated zucchini until blended.

In a separate bowl, sift together the flour, baking soda, baking powder, and cinnamon.

Stir in the chopped nuts and raisins to the dry ingredients.

Combine the wet and dry mixtures using a spoon, mixing just enough to moisten the ingredients. Avoid overmixing; some lumps are okay.

Pour the batter into the prepared loaf pan.

Bake for 1 hour, or until a toothpick inserted into the center comes out clean.
