You need to be real careful when selecting a camshaft. This is definitely an area where "if some is good and more is better then too much should be enough" just ain't gonna work.
Be very, very honest with yourself regarding how the vehicle will be used. If all of your time is spent at 3000 rpm, it wont do you any good to spec a cam that starts working at 4500. Increasing the "area under the curve" (camspeak for lift/duration), will tend to move horsepower and torque peaks up the rpm ladder - getting carried away can make them unreachable and the wrong combination can make them unfindable.
The camshaft controls too many events in the motor to simply throw in something lumpy and expect miracles. A properly thought out package of modifications can maximize the bang for your bux.
A really good resource can be found at
http://www.compcams.com . Take a hard look at their on line "knowledge base". I've talked with their tech department several times and found the folks knowledgeable, and quick to help.
BTW, if you're looking for cheap horsepressure, you wont go far wrong with a PROPERLY set up nitrous system. Dollar for dollar, this is likely the most efficient way to call up ponies only when you want/need them.
