I learned it when I was about 19yo. My late buddy, Art, was putting a turbo hydro 350 behind a 327 in an old Chevy van. I was helping him. We couldn't push the trans bellhousing up flush to the engine, so we used the BH bolts to draw it up. We had it almost drawn up when we heard a huge metallic "sprong". We looked at each other as if to say, "that didn't sound good." We pulled it back apart, and the front pump was broken.
