Default belt length with underdrive?

I was wondering if anyone by chance has a underdrive pully and knows there belt length? I would take mine off and measure it but Im kinda in a rush for time.

P.S I did a search and I didnt find what i need to know.

Thanks in advance.
Jeremy

I have found that the two different brands that I had were different lengths. Do you know what brand your underdrive is?

I dont have a flippin clue what brand it is. All I know it is black and it's an underdive pulley. If any one has a belt length I will get it and just find out which one fits. IM just not shure what lenght to get.

it would be even better if i knew my belt length. I would take it off but that requires me to get under my car, and take it off. But i would have to do that at the parts store cause i dont have my other car here. UUGGHHH

My BBK underdrive pulley required a 3" shorter belt. Look for a 6 rib serp belt to be 61.5" long to start with. The Dayco # is 5060615 or a Goodyear # 4060615. These are both of the manufactures best made belts. The cheaper belts don't last as long and slip more often.

My underdrive pulley uses Dayco part number 5060590. Don't remember the brand of the pulley, I put it on 9 years ago.
