There was 2 Cheyenne Super's there Saturday, the one above didn't have the hood open so I have no idea what power plant he had. The other one had a TPI small block in it. Sticking an LS power plant in one would be a cool project, a few have done it.
This is a project I WILL eventually do. Although it will be yeeeeeeaaaaars down the road. A 6.2/6 speed combo and a modern suspension on air bags, in that truck would be sweet.
Be sure to make a build thread!
