Yep, you can. I have a 3.47 jackshaft and a 3.00 sc. The problem with changing the jackshaft pulley is that you'll need to add a spacer to the sc pulley and idler pulley because the stock 3.2 jackshaft pulley is a different offset than the vortech pulley you'll be replacing it with.

I forgot to add. If the sc pulley is changed to a 2.85 (with the jackshaft pulley remaining stock), then you'll need to change the tensioner pulley to a 3". That part # is Gates 36225.
