Toyota's 5.7 Liter i-Force Cooling.
So they had a 5.7 Liter i-Force apart on an engine stand at the local dealership a family member of mine works at. The just of it was it's an American truck brought up here so there is the American/Canadian Toyota warranty thing (Toyota is one of the only companies that honours warranties for people that cross the border apparently from what I've seen/heard). The just of it was they could tell someone had tried to do some work/mod/play with it, who knows what, and it caused some bent rods on the engine and a few other parts to go. So they have the thing apart on an engine stand right now and I got to take a look at it yesterday.
I wish I had a camera. You guys would shat yourself at the cooling jacket around the cylinders. It literally makes the cylinder sleeves look like they are isolated and there is a "moat" around them there is such a big cooling jacket.

probably looks a lot like most open deck blocks ....
that's a honda block for example, most aluminum blocks are similar. Search "open deck" in google images, for more examples.

yeah, that's an open-deck block design. Better for cooling, but the bores can shift under extreme loads. That's why a lot of the honda guys who are revving them realy high, or running a lot of boost through their open-deck motors either tap some studs into the block to hold them still, or fill them with a concrete like solution with the same thermal expansion properties as the block.

You see the clearances between the sleeves and the block in that picture on that Honda block? Well the Tundra's if I recall correctly are at least 50% more then that.
