hehehehehe, sorry not my problem, i can write one in a year, hehehehee.
And no im pretty sure u dont, since the EA came out with both engines, to my knowlege u dont have too. So long as the motor has the same code as the motors out of ea its legal. If u put in a 4L then yes, or a 5L, u need to do some work and then see an engineer but 3.9CFI to 3.9MPI is no problem (very very sure)
Its my dream in a few years to re-make an EA GT, get a 5L out of a EL falcon, work the tits off it, stroke to 351, get a nice EA, buy a EB GT interior.... u get the idea, its alot of hard work and is very expensive but im sure it will be worth it :)
