Thanks for the comments. My calculations show at 75 mph, I should be at:

2,197 rpm for 3.54
2,054 rpm for 3.31

Most of the highways in Texas have 75 mph limits, which means everyone drives at about 80. I wanted to be able to drive on the highway without ear plugs.

I told Brent the engine will be mostly used below 4,500 (city cruising) so he is aiming it toward low and mid range torque. I'm confident he will hit the target.
