apparently A&A is licensed by Chrysler on these intakes,,and u can get different date coded 1's also! either 1962 -63-64,,underside of intake at the carb mount area there machined to accept after market valve covers(some anyway)for those higher lift cams(me).....they serial number them also and stamp A&A on them along lower rail so u cant pass it off as an original...all stage 3 only..and the serial number is stored in a data base locked to your name..interesting stuff.....it will be here next week..probably after the 4th .....now I need to sell some stuff..lol.
