    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

    Most likely, just changing carbs will not gain much for you, unless your stock carb is very restrictive (which is possible). However, the gains you can get come into play since you'll likely have to change intake as well, and will be able to use a better flowing intake. Beyond that, basic upgrades are always headers, and then cam/valvetrain. If you don't want to get into the engine, then headers/carb/intake is a good place to start.

    From the looks of it though, 4bbl intakes for the 3.8 aren't real cheap. googling gave me this provider:
