Should I leave it Stock?

I have a ‘65 Dart GT with a 273 2 barrel. (It was built the last week of production for that year which I am not sure actually matters.) It is a nice fairly clean example and am in the debate in my head of if I should make some changes come winter. I don’t want to ruin the car for whoever the next owner is but would like to have a little better performance then what the factory 2 barrel had to offer. I already picked up a D4B as I am not sure what I am going to do but they seem hard to find so when one was listed on eBay I scooped it up.
Is it a waste of money to put an intake, 4 barrel, and headers on a stock 273? Am I going to ruin the appeal of the car by taking away from its originality? If not should put in a mild cam as well?
It is mostly a street cruiser but I do want to have a little excitement getting on the freeway. Thoughts?
I felt the same as you do did some small mods to the little 273 which responded well than got hungry for more punch . The car represents factory exterior interior besides the wheels but I changed the heart and running gear and have it where it puts a smile on my face every time I’m in the saddle. As mentioned life is short enjoy it !
