underdrive pulleys
underdrive pulleys i have 2 options, b/c i broke my c-shaft pulley. get a billet alum. cs pulley for 72 bucks off of summit. or the jegs bbk set for 69. its an lt1 but what do you guys think... and also what size serp. belt will i need. btw, i need help quick cuz i gotta order this stuff.
Sounds to me like you are trying to blow up your motor by replacing a shot stock damper/pulley with just pullies.
If the damper is shot you need a new damper, now you can go with a new damper in a smaller diameter and accomplish the accessory underdrive that way ASP and ATI come to mind.
I can see buying an underdrive damper when you need a damper anyway.
Pullies for the sake of just underdriving the accessories is usually near worthless. It is a good mod on cars where the waterpump is belt driven but that is not the LT1.

ok caprice you are right my mistake. they are the same thing. but since they are one piece, isnt the pulley itself the whole thing. i mean, the 3 bolts in the pulley looked like they were loose enough to rattle and it caused the puley to grove itself out. i dont understand why the damper is bad. i need to take some pics but my pc program is screwed up.
