I bought this to rebuild and put in my K20 but since I got my new truck I can't afford it anymore. I tore it completely down and cleaned it up. It's a 2 bolt main 1976 engine. The bores look pretty good...there's a little surface rust in some of them but most of them are fairly clean. It has never been bored. Stock motor with under 100k on it. I took pics of a couple of them. I'd like to get $300 out of it. The only problem is the mains will have to be matched up again, I kinda goofed and forgot to mark them (newbie mistake). Here are a couple pics with a link to the rest of them: rest of pics are at http://mypage.iu.edu/~jwreding/400/ I'd prefer it be picked up but I can haul it a few miles if you're close by.
