Default Whipple pulley different for 5.3 and 6.0??

I bought a whipple kit that was on a 5.3 and i am going to install it on my 6.0 SS. Are the pullies different for the two motors? If it is, what kind of boost will i be running with the pully that is on the blower right now?

Yes, the 6 liter will need a smaller pulley to make the same boost. My experience shows about 2psi difference between 5.3 and 6 liter when keeping pulley size the same.

Do you happen to know the size pully i will need to make it back to the stock whipple boost? (6lbs i guess)
