Preheat oven to 350 degrees F (175 degrees C). Place bacon in a large, deep skillet. Cook over medium high heat until evenly brown. Drain, crumble and set aside.
Place crust in a 9 inch glass pie plate. Sprinkle bacon inside of crust. In a small bowl, combine Cheddar cheese, Monterey jack cheese and flour. In a separate bowl, beat together eggs, cream, onion and green chiles. Add cheese mixture; stir well. Pour mixture into pie crust.
Bake in preheated oven for 60 to 70 minutes, until set. Let stand 10 minutes before serving.
