I am using a manually adjustable belt tensioner on my LS1 motor with a powerdyne supercharger. I am just a bit off on belt size and max out the adjustment with the stock tensioner pulley. I am looking for a larger diameter pulley to replace it. Thanks

You can get go to the local AZ/PA and look thu them. dayco makes the plasitc 6 ribs in 101mm (3.5) and 76mm (3.0). I change the sizesall the timeon GTPs for this. heres a pic if they wnat a refrance. And the guy/kid isnt cool to let you look thu them. Motor would be a 3800 supercharger seriseII (L67) the vin will be 1 if they ask. Pulley "8" is the 3.0 6rib, but thay also make a 3.5
