318 Advice
small block headers are awful unless you spend the cash on good ones. they will give you more power but definitely hold out and save as long as you can for a good set like tti or dougs. keep your existing exhuast, you arent going to really get any better for your current setup. i wouldnt go nuts with a big cam unless you are going to go with a little more gear and a converter with a little more stall. there are some good recomendations here. my brother had a 318 in his barracuda he just had turbo mufflers with dumps and and aftermarket intake with a carter carb and hv fuel pumpt, otherwise it was stock. it moved pretty good. i liek that car i checked it out a few times when for sale on my way home from work. definitely a good start to work with.
