Guys I am new to this forum. I have been doing some research and would like to know yalls opinion. I have a 2006 Chevy Z71 with the L33 in it right now. I am having problems wiht the engine and am thinking about replacing it. I would like to put a 6.0L lq9 in it since I have read that it is a direct swap for a 5.3 all I would need is the long block and a tune. I this a good idea or would it be better to just put an L33 back in it?
