Default Belt Length/Part number

I hate to be the guy to ask this question but after some research I couldn't find anything. I have a Gen 3 6.0 with a low mount alternator, no AC, and ICT Billet power steering delete pulley. Stock sized trunk crank pulley and stock water pump.

Does anyone know the belt length or part number for the belt I need? Just trying to save a trip to my buddies garage and stop at the parts store on the way there.

Thanks.

Last resort, run a piece of string around the pulleys and account for tensioner travel.

I have used string before, but i have found taking an old serpentine belt and cutting it works better and is more accurate. I "prop" the tensioner about the mid tensioning position and then route the belt. Make a mark on the belt. Measure and look up belt lengths with the corresponding number of ribs. Some belts are advertised inside or working length some are advertised outside length. I hope this can help

I like your method as it seems more accurate. In my defense, I did say the string was a last resort..... LOL

I was in no way discounting the method you described as I have used that method before. I had some belt issues when doing my LS swap and found the method i described as very helpful to me on finding the correct length I needed.
