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?
