Yes it should be able to be done without a problem. I'm saying this since I have done a few with a Tbird 4.6 2V to a Mark and a 99 Cobra engine and then 98 Mustang with a Mark engine. 2 of them had problems cause they didn't take my advise and go with my recommended FordChip. com. They figured they would try someone local and have since had problems. I'm pretty sure one of the two has given up and is now running a FordChip program.

The Mach I engine is basically a 99 - 02 Cobra engine as far as the EEC V is concerned.

I'm currently running a 96 Mark EEC V with a 98 Cobra program done by FordChip.

Yes it can be done, We had a guy at the dyno day in Atlanta / No Limit Motorsports that used the GT PCM and the wiring as well I understood. It made ~280 on the Dynojet and was a clean car.:cool:
