So, I'm heading out to look at the truck this weekend. The fellow who's selling it also has his race truck for sale. I had a good chat with him, seems like a decent guy and full fledged gear head. It is a full load 1980 Sierra Classic 10, a one year only "Alberta Special", 632 Merlin, dynoed 835 hp & 865 ft lbs, auburn rear end, 4.33 ratio, trans brake, 10.2 in the quarter on the motor and has lots more modded on it. It is the truck on the trailer behind the dually. Here's a link for your enjoyment.
