That is not going to be easy to recover at least not in my eyes. I would probably charge something in the neighbourhood of $1600-$2000 k to make that block serviceable to my standards. That block is going to be heavily pitted in critical areas like the lifter bores and cylinders. Main caps are the least of your worries-even 318 caps would work. J.Rob
