Hey guys, what size of belt do i need for under drive pullies for a 4.6? I know you can use a shoe string and figure it out but I'm lazy. I haven't put the pullies on and would like to get the belt on at the same time so I don't have to go running around. Any of you guys with pulleys remember what size you had to buy?

Ditto..I had Steeda U/D's that use the stock belt. Only suggestion would be to replace the belt if it has some wear.

Sweet, thanks boyz. I just assumed since I was changing pullies I'd have to change the size of belt too. I just put a new serpentine on after blowing my last one at 100 mph at the track. Not good when you lose your power steering and power breaks 
. The pulleys are coming in tonight so i'll get them on tomorrow. Do you guys feel a seat of the pants gain?

The water pump and alternator pullies are bigger and the crank is smaller. They are designed to even out.
