I was getting some new shoes at the mall yesterday and they had the Tundra and a few other Toyota's on display, The hood to the Tundra was open, and I was surprised at how small the engine looked, probably just because the truck was so big so it had a large engine bay, I figured it would be available in the next Sequoia, but I thought, maybe if it is this small it is what is to come for an optional engine in the 5th gen 4Runner whenever that comes out in the next few years. The air box was HUGE though.
