That is kind of a loaded question, we really need more info on what your intended purpose is and what you've already got.
Is it a weekend warrior for bracket racing, a pulling truck, mud truck etc?
Are you wanting more torque or just upper RPM horsepower or both?
In general a good set of flat tops, some good breathing heads, a 280 magnum cam, a performer RPM air gap and holly 750dp would wake it up nicely.
