I'm looking for information about cams. Is there a general, all purpose high performance cam, or is something I heard about them being trade offs, between horse and torque true? How do they affect the engine's performance, sounds, and reliability? I'm kind of afraid that cams will do 1 of several things...
1) Raise the horsepower by 20 or 30, but lower torque by the same. Or vice versa.
2) Make the engine real loud, like a Mustang with no exhaust.
3) Make the car run rough at idle speeds, or throw off the balance of the car.
4) Just mess the engine up in general.
