The most common thing to see in 400 block's is the main web's cracking down to the cam bearing holes . Did you have your block magged when it was apart ? The only other thing it could be caused from would be if the cam bearing bore's are factory oversized , or if the installation job was done extremely wrong . My guess would be the block is cracked though .
