We had trouble with the machining on the Indy block. It was pretty bad. Cylinders were .011 out of round and had .01 taper. Sleeves are thin too. Not to mention #5 cam bearing bore was way over sized and hemoraging oil on one side.
I'm assuming this block was ordered with the bores unfinished? Meaning the sleeves were installed and the inside diameter dimensions were the result of the press fit? I can't imagine a boring bar making a hole .011 out of round. You frequently mention aftermarket blocks having no availability, I have heard very few incidents (maybe 1) of Indy having issues with reasonable delivery times. Don't you own or work in a race engine shop? Order an Indy block with no finish machine work done, line bore and hone your mains, line bore your cam tunnel, cut your decks, bore and torque plate hone your cylinders, address the oil drainback shortcomings and be on your way, not all that much more work than prepping an old iron block.
