I just want it 1" longer!!!

heheheh. Just wondering how much difference UD pullies make in belt length? Do i get it shorter or longer with UD? I thought i had this figured out and did some searching on here, but i've gotten both answers from people on here. I'm using a FRPP a/c delete (moves p/s pump up), bypassing and removing the smog pump, and installing U/D pullies (but not the alternator pully). From what i gather, about 73.5'' is where i should start (without UD's). So what lengths should buy? Can anyone help clarify this for me?

Anybody!!? anything? i'm going to be doing this work in about 2 hours, and i'll be over an hour from the nearest part store! i'd like to have a couple belts on hand...
Underdrive pullies would increase the length of belt i'd need or decrease? They are larger diameter than stock pullies??

I got underdrives inst and the stock belt was way to long. I aslo have smog removed. So all I run is a/c power, steering, water, alt and crank. I had to get a smaller belt. My tensioner is new and pushed down so hard that my other belt rubbed against each other. Here is the autozone belt that I use. duralast 755K6 this should put you in the ball park of where you need to be. Try it and then go up or down one depending on your need.

most underdrive pully systems will work with your stock belt, you just adjust your belt tensioner to compenstate.
