"Would you buy a buick with a 300 hp northstar ohc motor in it if it cost 5k more than a buick with a 350 hp pushrod smallblock with the same warranty and cheaper maintenance cost? why would you?"
Not only that, Lazs, but the oh-so-modern Northstar Buick has WORSE performance than the old model with the 350 smallblock engine.
"My Lincoln is another example of a good place to put one.... even so... it fills the engine compartment from side to side while displacing only about 280 cubic inches."
My wife's Grand Marquis has that same engine, and not only is it huge for its displacement, it's lack of low-end torque is almost comical. I consider that car extremely underpowered; I can't imagine how sluggish the heavier Lincoln must be.
