November 27th block.. from what I've seen with HO specific birds...I would shoot for a few days prior to block casting and a max of 2 weeks post for date codes for heads, intake, carb, exhaust manifolds, distributor, rear (depending on HD POSI or standard) the alternator, water pump, starter isn't that much of an issue as these are wear parts.
