mach I engine swap

[wildstang281]

I have a 97 gt that the rod is knocking so I'm deciding to maybe go with the Mach I engine. I live in Washington state we have emission testing every other year. How to I go about the pcm? Can I use my stock gt computer or have to get a Mach I pcm. I do have a NGS tool that i know that u can pull the vin from the pcm on newer models. Will they be able to pull the some info?


thanks Nick
