Preheat the oven to 350 °F. Combine 8 oz graham cracker crumbs and 2 oz granulated sugar in a small bowl. Sprinkle 3 oz unsalted butter (melted) over the crumbs and toss to combine. Press the crumbs into the bottom and sides of a 9" pie plate. Bake until golden brown, about 10 minutes. Make the filling while the crust bakes.
Filling
In a medium bowl, mix together 6 large egg yolks, 28 oz sweetened condensed milk, finely grated zest from 2 limes. Whisk in 8 oz fresh lime juice, 4 oz tequila and 1 oz Orange Liquer. Pour the filling into the baked crust.
Return the pie to the oven and bake until the filling is set, about 25 minutes. Cool to room temperature then refrigerate several hours or overnight.
Assembly
Whip 12 oz heavy cream with 1 oz confectioner's sugar and ½ teaspoon vanilla extract. Pipe or spread the cream onto the filling.
Refrigerate until serving, serve chilled.

Notes
To make an alcohol-free pie leave out the tequila and replace the triple sec with orange juice.
