I have seen a few 4-bolt #351 blocks recently go for $6000 to $8,500. The corvette guys really drive up the demand for these. I just scored a nice deal on a fresh '67 L-88 with iron '67 dated #392 sq. port heads. The engine was bought over the counter at Berger Chev. in 1967 by the owner. Cool story.
Kim, guess where it's going.
