I know the 4.3 will do most people fine for the " basics" but I was just stating that for me the 5.3 would be better since I have a heavy foot and like to have some pep in anything I drive. Now if a the v6 responds to mods as well as I think it will it should be a full bolt on session away from surpassing the 300hp with ease and even better torque. Just imagine what this motor would be like in a small truck like a s-10/Colorado boy that would be fun.
