It's not really a matter of which engine is better. They are both really damn good power plants. The killer part is the lack of support from either the factory or the aftermarket for the Hemi. It is improving, but they are behind the curve. Face it, you can't swing a cat by the tail without hitting something for an LS. It was really that fact that finalized my engine swap plans for my Wagoneer.
Oh, and Ace, I'm still trying to get pics on the oil filter lines for you. The car I had on the rack still had the stock oil filter set up on it. Sorry.
