514 longevity?
Okay,
So, still playing with the idea of stroking my 460 and was curious if I could expect the same longevity from a 514 then if I kept it at 460? Ideally, I would like to get atleast 100k miles out of this motor, I would like to be able to drive it to events 10+ hours away and not have to worry about being stranded on the side of the road with a pretty hole in my block.
Thoughts, ideas, etc.?

For the most part, just look at how a factory engine is built and replicate it. Focus on things that make the engine more efficiant. If you're looking for 600hp, and 100,000 mile life, it's not gonna happen. The more radical the build, the less life it will have.
There isn't anything that's radical or dangerous about a BBF Ford stroker that inherently shortens it's life. The R/S ratio is still better than a BBC 454. You'll want to stay with a stroke of less than 4.3" so the piston doesn't get pulled out of the bore too far.

The two D9 blocks I have picked up both have the longer cylinder walls.
It also sounded like they discovered at Dave's block summit, (for the most part), that choosing a 460 block (early vs late) was really a crap shoot for finding a block with thicker cylinder walls for a bigger bore size. I think the block summit results are posted on the web somewhere, I don't know where though.

Yes thats the one he is refering too, if you download the sonicdata file showing the results of all the blocks, then click on #3 you will find my block that is currently being run in my race truck as a 528 cid stroker.
