pontiac firebird with 455 V8

1968 Pontiac Firebird Description

I have a 1968 Pontiac Firebird with a 455 v8 auto and power steering.
This car has been sitting for many years and has lots of rust. it will need a full restoration. I was told it belonged to a young drag racer who unfortunately passed in the 70's. the family parked his car and it has been sitting ever since. It has a 455 but it will probably need fully rebuilding.
my plan was to do a full restoration but my business takes up too much of my time so it is time to let go of the projects. I did not get a title with the car so it will come with a bill of sale only.
I have been asked a few questions and I thought I should list them here.
1: I have tried to turn over the motor by hand using the fan. I was able to get it to move around 1/4 inch at the harmonic balancer, but then it got hard again
2: while I am no expert the frame looks repairable to me but please come out and look yourself to be sure.
3: No it is not derivable and the motor does not start.
4: The floor pans will need to be replaced as well as a lot of the sheet metal. I have added a picture of the floor pans.
From what I can see the date code on the head is L131, Casting is 7M5. Engine code looks like 22A154303 with VIN looks like 269957 YA so someone told me the Motor is late 1971 so for a 1972 B body model (full size car) 455

Thanks for looking.
