In one of those phases right now where it seems like nothing goes together like I expect, no matter how much research and planning I do. I was mocking up my water pump (Edelbrock 8842) on my car today and am having an impossible time understanding the bolts. I ordered the AMK kit for a '65 289 w/ alternator and AC from NPD, which comes with a diagram. OK, easy enough...not so much. The bottom left bolt (facing the engine) stops about 1" from the pump. The timing cover is a brand new Drake version, early style for aluminum pump w/ no backing plate. All holes were cleaned with a thread chaser before I put the timing cover on, so I'm pretty sure there's no issue there (plus the bolt goes in like butter until it stops). Can anyone help me understand what I'm doing wrong? I tried to search for a diagram or someone else with the same problem and came up empty. I don't think it's an issue with the Edelbrock, as it appears dimensionally the same as the old pump it's replacing. It's the bolts that I don't understand. Thanks so much for the help - this was a big frustration for me tonight after I was hoping for an easy project after wrestling with my carb rebuild.
