original restoration or modified?

Hello, my name is Jeff, and I live in Rio Rancho New Mexico. I have been a Ford fan for a long time now, but I really like a bodies as well!! My friend mark has a very nice mopar, it's a 63" Dart (Im pretty sure it's a 63') He has done a lot of mods to his Dart. It's very fun and good looking. I think he posts on here, but I'm not really sure.
Anyways, I'm getting off topic a bit. Here's the question to everyone. I got my first mopar (yeah!!!) It's a Dodge Demon. I really like it quite a bit. It's a good runner right now, paint is ugly and could use some interior work, nothing too major.
I'm curious of what should I do. Now, for collector's value, it would be better for the restoration to be correct, but I'd like to make some mods to it, as I'd like to have more power and punch. What does everyone think? I'm not sure what to do. I don't plan on reselling it. I am planning to keep it. Thanks everyone who can help me decide and get started!!

Thanks a bunch!!! Sincerely, Jeff D.:wav:
