How many motors can you smash the gas pedle to the floor and bounce the rev meter only 1000 rpm shy of redline for literally hours at a time, and not only not have it blow up, but have it return a reasonable gas mileage and still keep on ticking for many, many more years to come. I know mine can.

They remind me of the light aircraft engines. The light aircraft engines don't make a ton of power of maximum power compared to thier displacement, but are designed to run at 70% power all day long, whereas most car and truck engines are designed only run maybe 20% maximum power all day long.

What's the point of having a big heavy motor that has a lot of maximum power, if at the same time it's going to eat fuel and wear itself out faster than a smaller, lighter motor that's built to run full duty for longer periods of time?

So, since most of us drive empty trucks, we are putting less stress on the motor than it was originally overdesigned for and therefore, most of us can get many many thousands of miles.

Does this mean the 22RE is better than the 3.0 V-6. Well, that wasn't really my point. I think the 3.0 V-6 was designed with the same high rpm high load use as the 22RE, and the fact that the same block can easily support twice the power in the 3.4 liter versions, it's clear it was a tough design. Toyota just screwed something up in the headgasket area. But the 22RE does tromp the 3.0 V-6 in gas mileage, even under high rpm, heavy load use.

I was more comparing to the non-Toyota engines out there like the Fords and Chevys. Those engines run at lower rpms and far less than their maximum power most of the time, yet only last half as long as the Toyotas. Just proves Toyota designed a great motor.
