Underdrive Pulley Owners???
And from what I heard it was the Old ASP pullies that had problems with the double roller.
the corvette one i guess hase a deeper lip and goes further into the engine, why the back part of the pulley has to be machined off if using it on a vette.
Stock alternator pulley is fine unless you have a big stereo.
I have a double roller. They had that problem with the early ones. People had to machine down the inside face of the pully where it went onto the crank. Could be done on a bench grinder. But that problem has not been for years.
Rest of my mods are in my sig, if you are curious.
