Depending on what you want to do with the car, you really dont need to change the pulleys unless you going to track it. The cold air, throttle body, gears, cold stat, plugs and tune is more than enough on a street driven car. if tou gave some room, take it up to 3000rpm in second and punch it. Make sure you wear a diaper.Thanks man. That mirrors the good advice I am recieving from others who have been there to, and even a bit more info than most have said (thanks again). I do appreciate it greatly. My thinking is the same. When I do mod, I am gonna try the 3.73 rear gear, cold air, theottle body and tune. Already working on the plugs and colder t stat soon. I was thinking about the upper SC pulley but I would rather air to the somewhat safer zone versus pushing her too far for a few ponies more after reading your input.
