318 horsepower

Hey Guys and Gals,
I am new to this site and I like what I have seen so far. I have a couple of questions for the group that maybe someone can help me with. I have a 74 swinger that I got for my wife. She wants me to set it up for bracket racing. I asked her how fast she wants to go and her response was, " faster than your Dad." : ) gotta love that response. He has a 74 Duster that turns mid 12's with a 360 4SPD. I picked up a 318/727 combo for it. What am I going to have to do to it to get those kind of times out of a 318?

Any suggestions are greatly appreciated.
