I am looking for info and a market value for a 67 Firebird that my wife inherited. It, as far as I know, is a factory model 400 with a relatively recent (+/- 5 years ago) rebuilt 455 under the hood. How can I confirm if it is a true 400 or a fake? I have pics but don't see any option to upload them.
This is definitely more of a go car than a show car, headers, high rise manifold (hood is raised in the back for clearance), rear end locker.
Under the hood is a 8 out of 10. Interior is a 4. Body gets a 6-7.
If it is a 400, is it still worth more than a base model with the mods?
