72 Demon 340

What did the chassis guy do to screw up the car? Engine on the K frame or plate? If you sell the engine is the car runnable if another SB id dropped in? What is needed to get it back on the track assuming a SB is ready to drop in?
He did a shoddy job setting up the ladder bar suspension. It works but is not installed properly. Engine is on the stock mounts. This car could be raced as is or easily put back to street/stock. I have the numbers trans for the car too.
