Bill,
This is just a question but since you have so much documentation maybe you can answer it so I can show it to some people here who are questioning my sanity. My doctor, attorney, & etc. When I told them that several of the GT-500 Mustangs actually had 390s in them they officially declared me insane. I know the KR version used the 428 Cobra Jet but is there any documentation on just how many of the others had which engine?
Thanks,
Ron
