Actually 4.10s would be perfect for this car...with the stock 8400rpm rev limit and the stock 3.85 gearing you would still have to shift to 4th. Except it would be right near the end of the traps and this would hurt the times as the car will be off the cams when shifted and not near its peak after the shift. With 4.10s you would shift earlier before the traps, putting the car closer to the power peak and crossing the traps on the cams.
