You guys are so good, but nobody has asked a question I haven't though about.

First lets do the general question about moving down the road, then I will address Kerry's excellent questions.
It takes X amount of energy to move Y mass vs drag/ mechanical load. It's why we get the same mileage no matter what gear we put in. The ls motors at best are 5-10% more mechanically efficient than the 455. That's less than 1 mpg. If I find a way to get around basic physics, I won't ever hang with you guy again, I'm going into space.

That being said, it takes around 100-125 HP (some smart peoples best guess. For reference my HHR SS only needed 40 hp to run 80 mph)to move our coaches done the road. So if we had only 125, it might run 65, but it would take days to get there. So, as long as we stay in a range where the motor can make 100 hp we will move down the road. Extra HP just makes it more fun to get there. The nice thing is modern fuel injection will figure that out for us.

So the short answer is it will be fine, any gear you run. Look at your trucks, it will pull down the road that 4 ton trailer at 1800 rpm until you hit a hill and need more power. Then it adds fuel until it can't compensate, then it down shifts.
