can't you determine if it is actually the original motor that came with the car? such a beautiful middie with even a non numbers matching 2.7 done right will hold value over the 3.oL motor transplant everyday. if you are going to pay to rebuild a motor it cant hurt maintaining the originality/desirability/value the 2.7 presents.

i know certs of authenticity from porsche now for our cars is stupid expensive, but aren't there other opportunities to find motor numbers or even docs you may have in hand? that car seems like it would have it's original owner manuals around. i seem to recall motor and transmission numbers in the docs of my ultra original SC and bastardized 75 manuals.
