I will be running the pulley that comes with the whipple which I believe is a 3.50'', billetflow idlers w/ newer style snub ( 3 100mm & 1 92mm ) a 4 lb metco lower kit and a 3.2'' alt pulley and a notched stock tensioner. Can someone with past experience please point me in the right direction, the good old search has left me hangin', thanks in advance for any info.
