Heat oven to 350 degrees. In a saucepan, combine sugar, syrup, bourbon, and butter and bring to a boil, stirring constantly. Remove from heat and let cool to room temperature.
Whisk the eggs, cream, and salt together, then whisk them into the sugar mixture.
Pour the toasted pecan pieces into a pie crust, then pour in the batter. Evenly distribute the pecan halves on top of the pie in concentric circles, starting from the middle.
Bake for 45 to 50 minutes, or until the filling is just set and the crust is golden brown.
Allow to rest for at least an hour, then serve with whipped cream or ice cream.
