FYI
According to Ford press materials, engine was a 6.0L V12 with quad turbos. Preliminary power was 770 hp @ 6600 rpm and 650 ft./lb. @4750.
Engine was constructed from two Modular V8s that had two cylinders each trimmed, then welded together. Specially, they were Romeo versions used in Lincoln Mk. VIII and it was constructed by Roush and company.
According to a Ford engine engineer, this V12 was odd fire, since it was a 90-degree V. Even fire V12s are 60 degrees (+ -). Apparently the firing pressure curves overlapped so it "felt" smooth and NVH wasn't an issue.
