I seen this on eBay--

They say it has Full Thrust Crank Bearings To Eliminate Crank Walk.

Anybody know the truth in that?

Any motor can crank walk. There is no way to "eliminate" it! People that take such good care of their motors get crank walk. Personally, from what I have witnessed, after you mess with the Thrust Bearing in a 93-99 block you risk the chance even more! 75% of the 7 bolts that I have seen built have got CW. I havent seen many, but I have seen enough to be skeptical about them! Anyways... I think those adds are all full of shit.

now if it were a 6-bolt... different story...
