belt sizing

[DMBcentral]

i searched and didnt find the answer to my Q so here it is. I have a 89 5.0 and i am taking out the smog junk. I am putting on underdrive pullies, and keeping my A/C. What size belt would work for me? Or would I need to get a smog bracket and pully? Thanx a bunch

get an 83 1/2" and an 84" then take back the one that doesn't work as well.

i am using an 84 1/2" and it's starting to get out of range, i need a bit shorter, and i don't have ud pullies, so you'll need just a bit shorter than me.

i used to use a 69 1/2" belt on my old car to bypass smog and PS , the same belt is too shrt for me now, w/ no ud's by about 1/2" or so. maybe an inch even.

the belt numbers run like this....

ko60835

that means.... ko60 = 6 rib 835 = 83.5 inches
