I got a '03 GT (automatic) and I'm thinking about doing some type of stage 2 cam... Am I going to have to do anything other than Valve Springs? Do I need 3.73 ring and pinion, Torque Converter Upgrade, anything like that or can it just swap the cams and springs?
With a stage 2 you can usually just swap the cams and not get into springs & retainers. Gears and higher stall converters are generally needed for stage III and higher.
