the motor would be inside the cab at least a foot or more or sticking out through the grill that far.
the inside of your toyota would have a motor cover about the size and shape of one in a full sized van.

the thing is a huge 6 cylinder.. just don't see anyway for it to fit. really if you left the front of the truck alone the motor would be about where your transfer case shifter sits now.
not to mention the radiator, cooling. those things are HUGE.
