I am a proud new owner of a 1968 fastback 289. It has the original 2brl carb. I am looking to add some HP. Would replacing the carb with a 4 brl be the right thing to do? If so, what kind do you recommend? Is changing the intake a good option? I am interested in any other ways to gain some power with out doing anything major to the original motor. Any ideas? I am new to these forums as well so any help is greatly appreciated.
