Here's the setup I've come up with for my application. Of course not everyone will be using it. But it should work with the stock belt routing. The pulley is a 300-202 pulley from Dorman. I had to use longer bolts to mount the pump and shim it further back with washers. At first I tried to simply push the pulley in with a large nut around the shaft to move it further back on the pump shaft. However, it will bottom out before aligning with the belt and lock up the pump. So shimming it with washers and longer bolts is easier. The belt should route good on a stock belt drive setup. I just have to make things difficult by strapping a procharger on the side. The one downside is that the pump will be overdriven now. But this is a big block and I don't plan on spinning it up past 6K.
