Should waken things up a bit. I made the move from 2.73 ro 3.42 in my IROC and it was more responsive. I'm about to make the move from 3.42 to 3.73

2.73s to 3.73s should be a real good improvement. That's what I'm about to do since I got 2.73s also.

I never checked mine, but with 373's I noticed a increase in fuel consumption. If I had to guess I would say a loss of 2 mpg, but its worth the gain in performance

put in a ~ 3000 stall torque converter. Car will be MUCH faster and highway mileage unchanged.

going to 3.73s will feel like you've lost overdrive on the highway.
