Gas tank is out of a 92 firebird - TPI 350.

Well This project started with a bare cab and a rolling frame and bunch of sheet metal from a wide number of trucks. So yes is a real frame off conversion. I grafted a 79 Nova clip on to the front and then swapped out the torque tube rear axle for a ford 9" Now if I want I can bolt in any GM powertrain from a 6 to a big block.
