Got the Charger up on the lift to mock up the drivetrain...
Mounted the cast manifolds first, which are from a 6.4L Jeep Cherokee SRT8. These headers are cheap and they actually came factory on Jeep SRT8's which had 485hp, so they can handle the power and won't break easily. I paid $125 plus shipping for them. The driver's side engine mount had to be redone to accommodate the cast headers. The mount was originally straight...now it is curved.
