Yeah,..it has to be a hoax, or worse, a scam. I haven't seen pictures of this guy's alleged car or where the car is.
For the record, as stated before here on this site, my research shows the Tirebird I own is the only one left of the "show" cars.
According to all the articles I've read, BFG had 6 Tirebirds, one race, 5 show, all 70 or 71's built by a Southern California speed shop. The race one's had the real stuff, while the show's had 400's or 455HO's There are a couple of race Tirebirds owned by Mark and Linda Mountanos. But they don't have an LS6 in it, just a 500hp, 305!!!
Here's are the links to the two racing Tirebirds:

By the way, if you click on the schedule at the above links, you can see when to watch these cars live.
