Slack in new timing chain

Goo! 3/4"? What kind of block work was done? Moving the crank centerline up? That's some ugly slack=especially for a new chain. Even if the crank was turned, the timing set should be nice and snug. When I pulled my old one off, it was probably as bad as 3/4" and when I replaced it with a new unit from Summit, the slack was all but gone...then I drove it 10k miles, and it was bad again :(

Maybe not that much, 1/2 inch may be more accurate, but it's just not snug like a new chain should be. It was align bored (I think that's what it is), my uncle was saying that could be why it's so loose. It's a comp timing set too, so I would think it would fit better. It just feels like it's already drove a few thousand miles with the slack it has.
