water pump radiator problem

I have a 69 340 with the stamped timing tab and I have the timing tab from my 273 on there just in case I have issues. The Milodon water pump I got does not seem to get in the way of the driver's side timing cover tab on my 69 340. There may be some good info on this posting 273 to 340 swap

Here's the Milodon pump from Summit http://store.summitracing.com/partdetail.asp?autofilter=1&part=MIL-16251&N=700+0&autoview=sku

My engine with the tab. I have all the brackets from my 273 on the 340

Although, the cheaper route is to get your radiator switched it seems.
