Pumpkin Dump Cake

I made this for Nathanael's birthday proper, since we were having a chocolate cake the next day at his party.  Notice the 34 pecans for his 34th birthday?  :)  The cake is perfect for the fall.  It is so very rich and filling, so small pieces do the trick.

6 eggs
1 1/2 cup sugar
3 cups pumpkin
2 cups evap milk
1 tsp vanilla
1/2 tsp salt
2 tsp cinnamon

1 cake mix or equivilant
1 cup butter - softened
pecans

Mix the top 7 ingredients and pour into a greased 9x13.  Cut butter into the cake mix and sprinkle by spoonfuls onto the pumpkin mixture.  Bake at 350 for 50 minutes.  Sprinkle with pecans and bake another 10 minutes.
