Water pump shims?

906 Views 2 Replies 3 Participants Last post by  Malibu Jimbu
I have an interesting problem. When I tried to install my Weland water pump on my 327, the water pump "arms"(the ones that are bolted to the block) do not make contact with the block. The base of the water pump hits the timing chain cover(aluminum). I grinded down the small bolts on the base of the water pump but still, no luck. Have any of you guys had this problem? It looks like some shims would fix the problem but I could not find any. It is about 1/8" from the block. Thanks

I just installed a Weiand water pump on my small block, and although I didn't have your problem, I had to get shims to space the pulley fwd for belt alignment and had problems getting the alt bracket to mount at the pump. I had to grind some of the pump at the brkt mt holes and the the brkt itself for clearance. Didn't realize therecould be so much difference in water pumps.
