dont just stick a cam in your car and be done with it. You need to do it all at once to get the best bang for the buck. Heads/Cam/Intakes for your given short block that work best with it (custom grind the cam not out of the box crap like an E303...) the 5.0 can make great power if you do it right... might be a bit on the expensive side but thats what speed is... money = how fast you want it to go lol.
