If it was 1999, I would definitely consider running the factory ECU in a 5.0 mustang or a 3rd and 4th gen firebird, but you pretty much need a time machine in order to get the software and a computer that will run the software. And those early handheld programmers have mostly faded away into the pages of history. The factory stock cars are a tough one too. I don't know about all of the years, but the Cobra Jet mustangs were using essentially a tuned up street mustang ECU. I believe the COPOs and Drag Packs use aftermarket ECUs from the factory, so that sort of makes the OEM ECU rule a moot point in a way for them.
