  I currently own a 77 8KCAB with an AEIO-320-E1B that is rapidly nearing TBO.
I'd like to upgrade this engine to a 160 HP by installing higher compression 
pistons. The local FSDO believes this should be no problem, but they'd like to 
see a previous form 337 where a field approval has been granted. Does anyone 
have one or know where someone who does. Thanks in advance.
