Not sure if it been posted here but Roush now has a new installtion center for upgrades, from interiors to motors. I have a '07' 427R and was looking at the new 540 Hammer.That come with all forged internal, rods, crank and pistons. dealer wanted too much but called the installation center. For 15K they swap your short block and blower out, upgrade the clutch. Sounds like a bunch but only takes five days for them to send you out the door with a 540-600 HP car that you like with the full Roush warrenty.
