Bob, I moved your thread to the General Discussion section. Your car is in the database from June of 2000 with a note that says your original block (which was cracked and sleeved) was offered to the owner of the car at that time from steven3b on this forum but was refused. From the notes it appears steven3b sold the block in 2007 but it doesn't say to whom so you might want to PM steven3b and ask.
Let us know how it turns out.
Ed
