Swapping in a hemi 5.7

We just got the 5.7 Hemi Crate and it comes with the PCM/ECU and all necessary wire hookups. For ours we are also getting Schumacher Specialties motor mounts and TTI exhaust headers (the ones seen in the latest issue of Hot Rod). The PCM/ECU on the crate still has the rev limited to 5700 RPM, it also is timed for premium fuel (93 octane).
