5.2l - 5.9l differences and more
I've been told in the past that the 5.9 is basically a 5.2 with different heads. Does anyone know if that is the case? I'm not the smartest guy when it comes to Chrysler engines. I'm interested because I am starting to think forward to what I will do when my 5.2l engine fails. I really don't expect it to but with over 160,000 miles I want to have a plan in place so that I don't end up with more down time than necessary.
Also, what bolt on (non-turbo/supercharged) options are a must for this engine. Obviously a better breathing airbox but what about manifold or throttle body changes? Headers? Exhaust? I'm looking forward to turning some wrenches on this thing when I get home from Iraq so I'm basically looking for ideas right now. I'm also interested in computer changes. I remember doing some research a couple years ago and options for programming the factory computer seemed limited. Is that the case?
