i have a 86 Thunderbird with a 3.8L V6 and was trying to get more power out of the motor and i saw changing out the carb from a 2 barrel to a 4 barrel would increase my horsepower but i was wondering if this was really true or not and what would be the pros and cons of doing this, also if there's any other way of improving my hp. if anyone can help me out it would be much appreciated, thanks
