Well if I knew for SURE I could order a 6.4 in 2010 I would wait and order one asap next spring. BUT with the way the oil situation is and if this country screws up and elects the obamalama the Challenger as well as the Mustang wont be around long and the 6.4 wont see the light of day. I could be wrong.
HOWEVER I bet that by this time next year I can get a superchip or hypertech programer to get at least 30-40 HP and maybe a couple other tweaks to get close to 500. IF not there is always the supercharger! I wont rest till every mustang I see pisses brake fluid in fear. [:@]
