Having an LS swap was a dream for most people just a few years ago but now you too can have an LS swapped or upgraded car. Using some smart combos you can have the torque of the LS V8 for less than the cost of a set of wheels. The LS series engines come in many configurations and range from 4.8L up to 7.0L with the 5.7L LS1 being the most common swap choice.
