problem with my position of my altenator.

I'm in the process of finishing up my 400 build. As I was trying different lengths of altenator belts I found that my belt rubs on the bottom of my electric waterpump. I have a 2 groove pulley on both my crank & altenator. I also have my 400 mounted by elephant ears. At which I have already cutout a section behind the altenator due to it hitting it for adjustment. I now have about 1 inch for tightening the altenator adjustment bolt which now gives me a small window for belt sizes. But whether on the front or rear groove the belts still rub. Is their a smaller BB crank pulley that I can use or even a smaller altenator. Do I move my altenator out from stock position. Please help.
The pictures don't show the crank pulley or the belts rubbing. They are for you to see my setup,ie waterpump and altenator that I am using.These picts are what I have on hand if you need something in more detail let me know and I will post it.
Thanks
