Not Ranked
I'm running 3.55 with 15" wheels and Goodrich TA's. Toploader box that has a 1:1 topgear. Engine runs at 2650rpm at 60mph/100kph.
The first gear is ideal in traffic. The c4 would obviously handle the ratio and you may need to look at the torque converter and what the stall is.

The lighter right foot would see little or no wheel spin, but you would need to watch accelerating in anger as you may end up with consirerable wheel spin.
As a novice here, I'm basing this on my '66 Mustang that has exactly your set up with 3.55 centre, the converter was a 2500rpm stall.
I'm sure if you place more details on tire/tyre size, converter details etc. you will get a more informed answer.
In the interim my $0.02 cents worth.. ![3d smile](http://www.clubcobra.com/forums/images/smilies/icon10.gif)
