HA! Got it, i know where you are getting at, i dont have to touch them for a long while since they are technology advanced and more reliable and less tweaks work needed than old 5.0's. wait and see in few more years, those 05-08 are amazing machines with few bolt on's that would go nuts on the streets which i'd like to avoid, better off doing it on tracks.
I will of course purchase another 5.0, it has to be in clean condition and well taken care of, long time to find one as i would expect due to being year 2008 coming soon, they are ranging from 15 to 23 years old (87-93).. can't believe how time have gone by.
