Hello, I own a 1964 1/2 Mustang with a v8 289 (3 Speed automatic) which i have owned for a year and a 1/2 now. I bought it during my junior year of high school for $5000. Since the time i bought it, i have had body work done and a new paint job, and various other replacements of parts and maintanence. I am now quite happy with how the exterior looks, but one thing is lacking, power. Recently I noticed my car is not in league with some of the newer cars out on the streets. I have a 4 barrel Carter carberator on it (not sure of the exact specs of it), along with dual exhaust. I am not sure if to much else has been changed since i do not know the full history of my car, that and i am not as knowledgeable about cars as i wish. I want to upgrade the enging performance, but in many ways i do not want to cut down on full mileage to much because it is still my daily driver. I am in college now and I am on a bit of a budget, I want to know some things I can do to help add better performance and Horsepower to my car. I have been considering building up the 289, but i am not sure what would work best, and not cost me to much money. At the same time I have also been reading about people getting newer 5.0 L and dropping them into older stangs. So any recomendations or builds you guys could recomend would be awesome. If i am being vauge or you need clarification ask me.
