The 6618 block has a 1969 Casting date, its definitely a 69 block. The 9's sometimes look like 8's. 6618 block was only 1969 mid year. Someone brought this thing back to life.
I dont think its perfect but from where it was, they did a pretty good job. Agreed it has had some rust repair. Tag and VIN off the car at one time. I would not pay a premium for it, but its already at $55K and I'm sure the crowd at BaT doesnt care as long as it looks good.
