Thanks for the replies! I will have them sonic test the block. Sleeving the block sounds $$$. If it was a rare block though I could see spending the cash for that, but this is just an ordinary 360, nothing special. I was just worried that the cylinders might be thin and weakened by being overbored that much, but it's not going to be a high revving powerhouse, just a stock rebuild with a slightly hotter cam than stock.

On a positive note, the heads and crank are darn near perfect.
