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

To be clear, I think the biggest potential issue with an 8HP is more if you run a motor that is a little high strung and carb'ed. The deep first gear of the 8 speed kind of forces you into running a taller rear gear, but that can result in highway RPM's that aren't to the liking of the motor. But if you gear it down so it is in a better range on the highway, you might lose the use of 1st gear. The other way to do it is leave the gear tall and just not use 8th. Either way, if your motor wants to run at 2,200 rpm for example on the highway, it get's hard to make both ends work well.

Bolted behind a G3? Other than rev'ing too fast or some kind of built G3, seems like it is hard to beat.

The nice thing is, you end of potentially chasing gear ratios people are usually trying to sell cheap or throw away. But it also means you can't buy the gear set new, even for an 8.8. At least the last time I looked anyways.
