That "1" can easily be made a "9"
I remember looking at a Z11 pace car with "original engine" in Arizona back in 2001. VIN stamped on the engine but when you looked at the casting date on the block it was blatently obvious it was a 1968 block with the lower portion of the number "8" chipped away to become a "9". Pitiful attempt and I ended up wating all those frequent flyer miles to look at it. At least I didnt buy it and waste all that $$$
