2.76 open to 3.55 Sure Grip...expectations too high?

There you go!
The only cure for that hole, long after stall, is more pressure, as described in the post. Or.... closer spaced gearing; like a 4 speed; which will prevent the rpm from dropping so far, and, since your average power in each selected gear will be higher, that points to quicker thru the gears. So there is another option, but pressure is better and probably less money too.
The higher stall, streetable stall, only helps you get off the line, and if you happen to downshift into a sub-stall rpm. Once you are accelerating past stall rpm, it'd pretty much all on the motor. The stator is still giving you something, but the shape of your power-curve remains the same, and if there is a hole in the power delivery, that will not go away.
But you can change the size of the hole.
With say a 2000 stall, and the start of the powercurve being say 3400, that is a mighty big 1400rpm hole.
With a 2800TC the hole is reduced to 600rpm.
With a 3400TC, the hole goes away.
Same goes for the A833 4-speed, with average drops to 72.5%. Shifting at 5200 The Rs drop to 3770, hole G-o-n-e.
It's funny, I saw an 833 for sale last night and started researching what it would take for the conversion. After all, I really do prefer manual vehicles - last 20 years that's all I've had. But, it's a little more money and effort I'm willing to invest at this point, especially since there are so many other points that need to be dialed with this car. I don't want to complicate things even further.

I broke a 3.55 7.25 SG friday night :) and had to replace with a 2.76 open to get to school on Monday :-( ...went from a rocket off the line to a freight train on the freeway, with as much acceleration......neutered!
Sorry for your loss...haha.

I'm goin' with this right here
If this is the case, I hope I can figure it out. I will say that the car IS faster. Definitely. With the 2.76s it really didn't even want to spin one wheel, now with the 3.55's it'll smoke both tires. However I'm getting some wheel hop and I'd like to get these weak springs off the car before going too far.

I tested cylinder compression with a new, good gauge and here are the results. I tested each cylinder twice, with the exception of #7 since it was low on the first two.

CYLINDER

1 - 130, 133
2 - 135, 134
3 - 131, 129
4 - 134, 133
5 - 136, 136
6 - 140, 139
7 - 122, 122, 120
8 - 137, 137

Now, with 7 being that much lower than the rest, I have a couple questions. What could cause this? Bad rings? Could this difference cause performance issues? How can I diagnose and solve the lower compression, and is that even enough of a difference to worry about?
