no. seriously dude... You need to start searching and figuring shit out on your own.
What's your reason for wanting an underdrive pulley? do you even know what it does?
like for example:
i would port and polish then cams and so on so on... bad thing i'm pretty tight but i would love to get an idea
This is rediculis.
First, youu don't port and polish your cams... The only thing you really do to your cams is upgrade them, unless you count tuning in the cam category...
Second, WE ARE NOT GOING TO BUILD YOUR CAR.
YOU need to decide what you want your car to do, and YOU need to decide what is in your budget. SEARCH around and find what people have done, where you can get parts, what suits your needs. YOU need to figure out if this car is your daily, weekend cruiser, drag car, autox car, ect... this is YOUR car, not ours. Stop asking people "what should I do next to make my car fast, y0!" and start building your own fucking car.
