My memory is clearing up a little and I can remember the particular car I saw. It was at Jeff Carachi (spelling) house in the Detroit area(vague, can't remember exact city). He said he got the Bird from the original owner and it was always Chevy powered. I didn't question it. The car was still all together and wasn't that impressive because I wasn't a big Chevy power fan at the time. I remember he seemed to be ready for me to say it wasn't true but I didn't question the cars validity/history. This was about 13 years ago. I know it means nothing without producing the car and vin but it is a little, very circumstancial, evidence. I remember that it had a 307 or maybe he said it was a 302. This was before I owned my 69 Z's so I didn't know much about the 302 at the time or I would have dug into it.
