Some friendly advice:
You are going to need to provide ALOT more information to get near your 10K asking price.
"9 sec stage II" that has never been in the 9s, and you don't know which block it is? You sure it's even a stage motor? I can understand if you don't know the motor inside and out, but knowing who owned the car when the work was performed would be helpful as I am sure someone on here knows that person and could get the missing information.
The need to knows:
Which block?
What heads, what work performed to them?
Cam type (roller / hyd) and specs?
Which crank? Pistons?
Valve train?
Oiling system?
Its out of the car now, so if you can't find this information I suggest you take it to someone who can. It will be worth your while to know what it is you are selling...
