Hi everyone. New to the forum and I am currently looking for a 65. I am not much of a car guy but have always loved the 65 GTO. I have noticed 2 things in my search. There are a few I have seen with non 389 motors in them. I have also run across some GTO conversions. I am not necessarily looking for matching numbers or original paint but was wondering how much difference do these 2 things make in the price of the vehicle. I'm sure all original with matching numbers would increase the value but I wanted to get some opinions on these differences.
