Modifying a 360 water pump

I read your post
You're in trouble.
I've never replaced a bearing in the LA pump, but If you look real close at that long nose, I have to wonder if it couldn't be shortened. Seems to me that might be doable. Just don't run it backwards. That might require some a creative idler arangement, cuz it would be on the wrong belt run.
Yeah, you're in trouble all right.

So inquiring minds want to know; what makes the engine immovable?
