Grab a 5.9, give it headers, a 750 carb on top of a RPM & a vacuum advance distributor. Use a A-500 transmission & 3.55’s spinning 26-27 inch tires. If you don’t like the performance of it when you get your car…….. PM me on camshafts that “I” would use. From there, you can ask 10,000 questions and drag your feet on a cam purchase until you feel good about the research on the cam you pick.
