a link to a page where they tear open the 4.7l
almost a hemi, aftermarket etc... stand -out to me

aftermarket - and Mopar Performance - take the 287? There's already a
supercharger setup from Performance West, and available through any Jeep
dealer. But less radical upgrades would seem to be quite easy. Revised,
premium fuel calibration - more spark advance, and a tad more fuel in the
form of a computer chip flash would seem to be almost a must. There's room
for larger valves, the Mopar machine shops are probably already plotting how
they'll re-contour and flow the heads; headers are almost guaranteed, along
with a less restrictive air intake setup, and Crane or Comp Cams will surely
have cams for it. In other words, we see no reason why this engine can't
respond to all the usual hot rodding techniques, and then some. In fact,
with such a bountiful set of basic ingredients, hot rodding this engine
seems a natural.....
