Gear vendor's with 3:54 rear gears and th400?

I am going to change my gears at this point I believe. I am going to add the gear vendors but you are correct 3.54 is too low. I'm building this truck to have fun in so fuel mileage isn't really a major concern. I like that I can get my rpms down and have it be a bit quieter in the cab and save my engine some wear on the highway. I'm just debating between 3.73, 3.92, or 4.10s. Would liven up the bottom end and give me a little on the top. My engine is an 275-300 hp 327 stock but will be rebuilt to same specs as stock.
