I've searched a bit in the archives, but can't find much on the subject. I've got my engine torn down to the bare block. It came from my donor with 210k, which means I should see some good wear to the bearings, cam, seals, and cylinder walls right? I don't. Everything inside looks really good. This came from a bone stock, never rebuilt 91 5.0. My question is this: I talked to a machine shop about cleaning and boreing .030 and the quoted me at $450, provided everything went well and the block isn't cracked. But, Summit sells a new bare block for $500. Even the guy told me that that was a steel. What would you do?
