Preheat oven to 350 degrees. Place pastry dough into pie shell. Trim dough to even with the pie plate. Place the pie plate on a baking sheet. Combine eggs, egg yolks, and sugar in a large bowl. Whisk together until well mixed. Fold in the corn syrup, butter and Bourbon. Blend well. Spread 1/3 of the chocolate pieces over the bottom of the pastry crust. Pour in the pecan pie mixture. Spread 1/2 cup of the pecans over the filling. Spread remaining chocolate over pie filling. Top with remaining pecans.
Cover pie crust rim with aluminum foil to keep from burning. Bake 50-55 minutes, or until set in the center.
