Hey guys im dropping my sc pulley from a 3.8 to a 3.4 what size belt will i need to run
10-20-2010
the thrasher site said 66" for 3.25-3.4 i just bought a 66.5"

You need a 658 IIRC.
10-20-2010
is there local places that sell it?
10-20-2010
Call around.

You can also just buy a 3.5" tensioner pulley for the SC tensioner and not change out the belt for that size pulley.
This is cheaper than buying a new belt

^^^ Exactly what I did and it works perfect.

I have the entire belt sizes also listed in the thread in my sig...just a FYI for future reference.

thanks blue gtp and i was going to buy a big idler pulley but the belts have 112k miles on them so i figured ide dish out the $ for a new one
10-22-2010
can i swap the idler pulley from 3 in to 3.5 in?
10-22-2010
Yes you can as long as the tensioner pulley is still 3" with a stock sized belt.
You MAY be able to bump both pulleys up to 3.5" with a smaller SC pulley, stock sized belt, and plenty of muscle power, but I don't know...
