There was no buildsheet under the seat, may be a few days before I can get to the gas tank.

Don't hold your breath on finding the build sheet - very few exist and are as rare as hen's teeth for 68s.
The good news is that the original tire pressure sticker on the glove box door is a dead give away. Its probibly the best indicator of a real 68 Z28. The other pictures point in the same direction.
Icing on the cake would be having the VIN on the MO block match the body indicating the original motor. I would suggest using that block to build a vintage, althought non-matching high RPM 302.
In any event, enjoy the car!
