A friend of mine said i should get some aftermarket pulleys and after thinking about it i should. i know that Grand Prix's have 3800 Series II Engines. I dont know about the bolt-ons/internals of them. could i buy an aluminum flywheel, water pump, alternator pulley and is it worth buying. im tryin to shave a little weight, build my ride stronger and produce better revability of the motor. if this is something i can do, then what type of pulleys should i replace? what type should i get as well underdrive or overdrive?

 

an overdrive pulley? no, that would be bad, i dont think they even make such a thing.

overdrive is for your car's trans not the crank pulley

all the underdrive pullies are basically the same
