Vibration Problems and need a short waterpump pn# - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I started a thread a few weeks ago about some vibrations that I had while the truck was at a stand still from 1300-1500 rpm. I thought that I had a bad waterpump pulley. I bought a new one and put it on granted the vibration is a little better but still there. I unhook the belt and turn it by hand and I see that the little hump that I see that the hump is in the waterpump itself. So its off to get a new waterpump I guess. I am heading straight to GM for this one. No more kragen for me. Does anyone have the pn# for a short waterpump for a 350?

Thanks

GM itself no longer carries a short pump. You'll have to buy a GM Performance Parts hi-po pump.

I buy new water pumps at AutoZone. They come in a yellow box. 100 percent brand new.
