Joe Bibbs Sc Belt

[radonfl]

I need to change my charger belt on my 05 gibbs 5.3. I suppose i will purchase a gatorback but how do i know what length to ask for? I wish to replace the 3.6 pulley with a 3.2 at the same time. Will i need a shorter belt or will the idler take up the difference? . My intentions are to install the pulley , 160 stat and have it custom tuned same day. Im hoping pulley doesnt require larger injectors.

I would appreciate any input you guys have on this.

I have the stock size belt on mine with the 3.2 pulley.It seems ok (no slip).I'm running a dayco belt though. The goodyear one is what i'm going to do with mine too.
