Used? For $3500 you can buy a brand new 6-71 Blower Kit for a Small Block Mopar from Dyers Blowers. That's everything. The Blower, Intake, Snout/Drive, Pulleys and the hardware to install it. (you pick the psi/boost you want, belt width and style and how many grooves you need on the v-belt pulleys and they build a drive assembly to match your order)
You supply the engine and intake manifold gaskets, of course :D
Dyers now has the specs for a 3-Groove SBM Pulley (as well as 1 groove and 2 groove pulleys), because I ordered that for my '74 Duster. I was the first person to ever order a 6-71 Blower for a 340 with Power Steering & Air Conditioning. I had to send in my old 3-groove pulley so they could build my order since they didn't have the specs on file for such a creature.
