Dan,
Thanks for the amazing amount of info in your post. I still have a few questions that I hope you can answer.
In your post, you say "The meat between the cylinder bores will be reduced by an amount equal to the increase in bore size creating more localized heat. However, the rest of the cylinder wall will only be reduced by half of the increase in bore size." If I read that correctly, the front and rear of the cylinder is bored .040, but the outside and inside is .020 over? Am I understanding correctly?
It is my understanding that the symptoms of the thin walls would be the engine running hot. At the bottom of the cylinders where it is most often the thinnest, would heat still be an issue, if there's oil splash down there as well? Are there any other symptoms that would result from this wall thickness?
In your opinion, would sleeving be a viable option? That could put the block back at stock bore, but would it hurt reliability and integrity of the block? I'd also have to find out how much it would cost.
And if they sonic checked the block before they bored it like i wanted, they would've been able to see the core shift and offset bore it safely, correct?
thanks again, you've been an awful great help.
