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.

like stlwagon said...new springs and retainers are not nessecary...those depend on how aggresive the cam is....with a stage 2...you will not....but if i were you..i would go with gears anyways...lol....i have an automatic too....and i am puttin 4:10 gears in next month..

I dont know where you would of heard that. 4;10's is the only way to go with an auto. I would suggest doing gears first it the best mod you will actually feel when driving the car. 1st gear slower thats funny! :headscratch:

I thought 4.10's in an auto suck cus it makes first gear slow at low RPMs? I could be completely wrong thats just what i heard
