anyone know where i can get a single groove alluminum pulley that the belt is right on the harmonic balancer? i need it right agianst it i have seen them but i cant remeber where its big block

I'm not sure who sells them,I have one from DMI,I think Mancini sells them.I got it along with a super-mini alternator and the DMI low mount bracket for it.

how far is the belt off the harmonic balancer? im needing one right against it

It sits right against it,I had to shim it out for my application.They make another one that spaces it out further,so watch what you are ordering.

i'd say the pulley that mike doty (mdi) sells is as close as you're going to get
