Help on Firebird pricing.

Hi, I am in the process of selling my 79' firebird formula, but the price is a problem. So I would like to ask for your help and how much would you pay for it.
Here's the specs:
Dark blue body (excelent shape/ no rust, the bottom looks like the old car bottom)
- The inside is great, back seats have no rips, and are original, driver seat has few rips and passenger seat has one rip.
- Floor is in good condition.
- The dash has few cracks, and the speedometer is 10 mph off. The clock does not work.
- It has 403 rebuilt engine, pulling around 370 hp (thats what the guy who rebuilt it said) In great condition.
- Bad headers (which are getting replaced)
- New Radiator, oil sending unit, master cylinder, ignition system and carb.
- Chokes a littlebit when cold, but its getting a total tune-up in next two weeks.
- Rebuilt transmission, works very well.
- 45000 miles (original not known)
I drive it very carefully and I take care of it. Usually I dont race, but in truth I did it twice against two mustangs. (and I've won).
When the headers are done and the tune up kicks in, this machine will be astonishing.

This is a little profile of more of what is wrong, than what is right with the bird.
Plus I also have a gold hood from a 78 t-a and I am in a process of adding a shaker to the formula.


Thanks for reading and evaluating, please give me a price so I can somewhat decide to sell it or not.

Once again Thanks a lot, you guys are great.
