Another cheap deal! I just pulled these out of a 305 which i didn't even know was rebuilt untill i stripped it down. They are 40 over sized with part number 454np on the sides of them. They also have all of the rods and are in perfect condition! The car has 65,000miles on it and this engine is rebuilt so they can't have had much use. Pictures are available if you are interested.
Thanks,
Tony
