318 top end build

Thanks for the advice everyone. The car is not stock right now. I don't pick it up until Tuesday so I'm not sure exactly what is on it. I couldn't take it apart in the guy's garage and he wasn't sure what it has. He was just selling it. I know it has a 4 bbl and an aluminum intake. The previous owner had installed headers and a full 3" exhaust. The headers have to go since they are killing ground clearance and the 3" pipe is killing my torque. Once I get the car home I will see what carb and intake are on it now. I'm also thinking of just doing a cam for now and swapping the gear to 3.23. That might be enough to keep me happy until I replace the entire drivetrain and drop in a 360. I might be good on intake and carb but i'm not sure. Thanks for all the help.
