Yeah plenty of elevation change around here, but that notwithstanding, I don't use OD until at least 60 mph. At that point I'm at 3 grand in D, you are as well naturally, same gearing. But I keep the rpm's at about 2500 or so. So much better there haha, just lay into it and it wants to moooooove. That's why I wrestle back and forth over this newfound power and torque I'll have. I'd like to go to 3.45's or 3.27s just to get it lower in OD on the highway for noise and wear and tear and I GUESS mpg maybe. Lol. But I always tend to keep it in a gear that puts the engine in it's power range. 3.73's just fit this car so well.

With the 2800 stall non-lock up converter and 3.73s I'm turing about 2800-3000 in OD at 70-75mph on the highway. It should be about 2400 rpm at 70mph but the converter slips about 400-500 rpm because it's a non-lock up. With the windows up and the A/C on it's quiet in the cabin. Noise and a down shft to 2nd gear is just a throttle blip away.

Keep the 3.73s and stop being a wussy

Interesting, Im usually in 5th in my fastiva by 30 mph

Nothing like accelerating from 1200rpm like most cars do from 2500rpm.

Then again I pretty much have the power-weight ratio of a corvette...

IMO the lower the rpm the better. Then again most of you guys dont DD your "fast" car.

All hail the Festivus!!! :hick: haha. I'll see what happens with a locking converter. I'll be grabbing dirty dog's locked version of the converter I have now before it's all back together. As Lou said it ought to drop 400 rpm or so. You're below stall speed at that highway speed, so it's gonna slip, waste energy and fuel. That's what drag cars do LOL, I want this car to be more like the car it was built as, so I'm going with lockup. I got this one second-hand reaaal cheap, so I said screw the lockup. But I can afford to pay for a new one now, so I will. A hardened lockup shaft will be in the mix as well, so I don't snap it with the valvebody setup and a GT40 motor...

I went non-lock up so I wouldn't kill the lock up shaft. After all I plan on dropping on a KB 2.0 blower one day..........:).
