Man, after all this bashing, I hope one of the members here isn't bidding on it and introduces themselves under new members next week. That could be uncomfortable, except for Todd of course.

I called Charley -- He refused to back me on the bidding. Told me "your skull, is extra thick"...
What is an "extra thick 396 block"? My recollection of 396's is that they were just factory castings... and that they were easy to window.
I'm no engine builder - heck - I can barely identify a cam from a crank... but I really don't understand the "extra thick" reference... perhaps he meant extra thick as compared to a standard casting -- but that could mean that the one he was lucky enough to have surveyed was a few thousandth thicker than "the other one" they looked at....
I Cut and pasted this from a build article in HOT ROD....
Dougan's Engine helped us survey the Merlin III block with a sonic checker, and we found cylinder thrust surfaces averaged 0.440-inch thick at a 4.490 bore, and would end up even thicker than World's guarantee of at least 0.225 at 4.625 bore.
Stock blocks are as thin as 0.300 inch at standard bore, and 0.285 at 0.060 over. Likewise, Merlin deck thickness and consistency is far superior to a stock block.
To get 468 out of a 396 - you'd have a bore of 4.185 and a 4.250 stroke... That's a .091 overbore - which can be done... but I wouldn't do it. Particularly not if I was investing 10,000 hours into a build!
