what exactly do underdrive pulleys do, and what price range do they run around?

 

They tend to be lighter, and reducing reciprocating mass always add's power (generally about 2.7 hp per pound you can remove). They are also sized differently so that your accessories don't drag on the engine as much, but beware, I've heard alot about them shortening accessory life as well. Depending on what year your monte is and what engine you have, look at Moroso, Edelbrock, stillen.com, and www.nopionline.com.

 

also FastForwardperformance.com sells them for the 3100 3400 and 3.4 DOHC

 

THANK YOU SO MUCH! I've been looking for someone who carries underdrive pulleys for the 3.4 DOHC I could kiss you right now.

 

that website isn't there anymore, atleast, no search engine I have used has been able to find it. Do you know of anyone else?

 

sorry... here it is http://www.fastfwdperformance.com/ that one works. i just orderd and installed my UD pulley for my 96 DOHC. i like it. wasnt as big a change as i expected, but it was good.
