Message I bought this bottom end mostly for the pistons/rods/crank/hardware. If the block wasn't 100% usable it isn't the biggest loss in the world but would love to use it if I can since it's already bored, line honed since ARP hardware was in it, galleys fitted with threaded plugs, etc so I'm going to post some pics. To my untrained eyes, they look ok, except cylinder 4 has the scratch in the pic, you'll know it when you see it. It may not show it in the 2nd pic but there is another much fainter scratch that barely catches my nail about 1/4 way around the same bore. The other cylinders look good to me, still plenty of crosshatching evident.

Anyways, here's the way the pics will go. There are 2 pics per cylinder, 1 from each side going in order of 1,2,3, and so on. Chime in with your opinions.












And here is a close up of the scratch in #4
