Restoring a car without documentation

That's a great car, with or without a fender tag and build sheet. The VIN says it's a 383 car and with the tons of pictures your going to take, you will be able to prove some of the other things on the car. It will never be as valuable as if it was fully paper documented but it's still a worthy save if you can do it. I'd feel free to hot rod the old thing just a little, that's obviously how it lived it's life.
Now, on to the 340 that's in it... What's the VIN on that engine????? I'd like to run it through and see if it comes back to a Mr. Norm car. I wonder if it has any ties to the Six Pack that was in there.
