You have close to the same setup I have. Depending on how much rpm you are turning a 3.4 pulley would max you out around 6500. If you turn more rpm then go with 3.55 pulley, this would be good to around 7000 rpm.

^^ What he said. Id just throw a 3.4 pulley on and let her eat! Should be damn stout!
