Those Running 3.73 And a TF w/ LockUp.. What's your highway Driving Like?

Those Gen 3 Hemis are happy at pretty much any rpm. No need to cruise at more than 3000 I don't think. Their 6 and 8 speed transmissions knock the highway rpm down to 2000 or less where the bet mileage is. Your call.
I've an 8 speed in my other swap (64 A100 Truck) with 3.55s...cruises nice at around 1900. Just trying to decide if 3000 rpm is gonna drive me insane
