Belt Size LSA Conversion 2.55" Pulley - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Hello,

Just completed an LSA conversion on my LS3 SS. It currently has the ADM 6-belt setup, stock LS3 balancer and the stock 3.0" LSA pulley. My installer has already convinced me to drop the pulley the size as I already have the supporting mods to support it, and the tuner has already said he'd retune it to the smaller pulley.

With that said I'm looking at the Griptec 2.55" upper pulley with a 10" hub. What belt do I need to go along with this pulley? I looked at the ADM belt size chart and for a 2.5" pulley it says

STOCK CRANK PULLEY WITH 2.50" ADM PULLEY GATES K061005 OR 1000 IS TIGHT.

Is this right? Any better options?

Thanks!
