Wow, 150 lbs. if the 6.0 is used will there need to be anything done to the front end to make up for that weight? Taller coils? From just thinking about the differences of the two I would like to use the aluminum block but the 6.0 cast will give me more pulling power for a camper over the 5.3. I dont want the 6.2 because of the premium fuel. I could always do a cam and heads on the 5.3 for more guts but then that is breaking into the motor, something I want to avoid for once with something I do.
