2.94 gears with a four speed.

I have looked around on various threads about gearing and still have a few questions. I have 3 built up chunks with ratios of 3.55, 3.23, and 2.94 gears to swap around based on intended usage. Occasionally I take long highway trips (400) miles each way, this is what I have the 2.94 gears for. From other posts I've read I see others who like the 2.94 gears in their rides but have the torque multiplication of a converter with auto trans. I have 28" tires and my concern is riding clutch to get rolling, I do however have a 408 with gobs of low end torque so maybe it won't be an issue. Any thoughts or opinions are welcome. I just don't want to under gear the car and prematurely wear out the clutch.
