3.73s are good if you got a 4 speed or a 700r4 .Any 3 speed  like a th350 or 400 is not good cause of the aggressive rpms it produces.If you got a 3 speed auto go with the 3.42.

thanks

What size tires are you running and what trans? I agree with Pat unless it's just a toy. If it's a toy go with the 3.73
