stock belt is working just fine for me on my 3.4. you can get a larger idler pulley if you like vs a new belt. if you think its slipping.

Either you installed it wrong or got the wrong belt.

And according to the guide from back when, which is in the thread I suggested you read...you're looking for a 658, not a 660.
