Thanks for the info. From what I have read and seen, the 5.2L V8 just
responds very well to various modifications and will yeild some impressive
gains without having to go internal; modded TB, headers, intake kit/K&N open
element, free flowing exhaust, etc. Maybe this is due to the fact though
that the 4.7L V8 is rather new and companies are having hard times creating
and implementing worthwhile modifications. I mean, from what I have seen the
headers shouldnt even be touched and they exhaust system is rather decent
also, so this really leaves just adding a TB and a cold ait intake setup,
right? It just seems by adding some rather minor parts(performance-wise) to
the 318 that the hp/torque figures rise rather nicely. Plus for maintenance
is overall user friendly-ness, the 5.2L is nicer to work on. Of course then
also, the 4.7L does need dist cap/rotor maintenance and the plugs are setup
to run for 100,000 miles, but I am still a die hard 'old school' Magnum
engine guy and dont mind changing things like plugs/wires/dist caps/rotors.
Still waiting for someone to convince me to buy a truck with the 4.7L V8 in
it..........anyone? Are there any towing/payload differences between these
two engines?
