sb 4 speed questions on 63 dart gt

I have a rebuilt 360 out of a camper and I have a 4 speed. Just thought I maybe could have a little more burnout fun with a sb setup instead of the six. Swapped 8 3/4 suregrip 3.55's and the springs that came with it. But... If I can find someone to set me up with one of those turbo headers and point me in the right direction..... Maybe that'd be more fun and different. Have a drag truck already so not so worried about how it will do on the drag strip just want something we can take to car shows, cruises and still light up the tires good on the back roads. Will probably still see strip action though when the trucks broke......
