I plan to stay N/A, after I get the tb and plenum you got, cams and heads will be next on my list.
-- Ability of cams to make power hugely dependent on overall breathing ability of motor. So, on mild motor w/just bolt-ons the HP you get will be lower as opposed to a motor w/excellent ported heads or with a power-adder (supercharger, etc.) Anything but basic cams (for example, Comp Cams XE262AH) will suggest/require that you also upgrade valve springs as the cams will produce their biggest gain in higher rpms. I still think 15-25hp is reasonable estimate of gain on your motor w/o going to valve springs or ported heads. Guys here seem partial to VT cams but do search here for cams and will get many other suggestions. You can make the car pretty unpleasant to drive and hard to tune by using "too much" cam.

Thanks for all the advise. I have ahd people tell me that I can get anywhere from 30 to 60 hp from cams alone. With what I have already done to the 03 mustang gt, what can I really expect(HP at the wheels wise) to get from changing the cams. Any type of cams you would reccommend.
