Would this be a deal breaker?

The torsion bar crossmember and the frame rails are fine, the floor pans are also good, looks like a professional floor pan replacement though. The 340 casting number matches the vin of the car and is included with the car. It is disassembled and in stock perfect condition. The owner removed it because he didn't want to ruin the engine in drag racing because he learned it was worth so much. He then stored it in his garage.

I also learned the 4 speed that comes with it is not numbers matching because it was replace by the original owner.

I could easily lower the price some more. He needs to get rid of it to work on another project.
yep
