Have an 88 IROC TPI 350 MAF....just want to know what are the best pulleys to get, where to get them and how much they cost......Will I see any improvement or are they a waste of my time?

 

In practical terms, they are a complete waste of money. You might get a slight gain (maybe 1 tenth) but in return you'll have poor charging at idle and maybe even poor cooling.
In other words, if you really want to improve your car, save the money for something else that will provide real gains.

 

I agree.

 

Yeah what they said. Dont waste your time, and if you do fee thel need to get them, just get a cheap brand. They all do the same thing.

 

I like the march brand of pulleys, just get the crank and alt. pulley set. Gains are in my sig.
