So here is the problem, I have a MAC underdrive pulley setup on my 5.0 and now I'm attempting to install my crank for the Vortech I bought. Doesn't fit with the underdrive water pump pulley, and I can't find one. Does anyone here know of a place that sells oem style pulleys? I've checked ebay and the only one on there is $60 shipped and its used. That is way too much imo.
