As the title suggests I want to swap to the LS7 motor for my off road duties. GM did it with the hummer H3 R . I do know that the transmission might have to be swapped (currently a 4L60) GM used the 4L65 in the H3 R. Also there is the issue of a dry sump system. Any help where I can get even a direct bolt on will be much appreciated. I want the vehicle to retain its 4 wheel drive system. Thanks
